returns a time zone for the given region name or UTC offset given as a string ("+01:00")

Parameters

name	the name of the region to find or a UTC offset given as a string ("+01:00")
xsink	if the given region is not found or valid or any error occur finding or loading the given region, exception info is stored here and the function returns 0

Returns: the time zone region found or 0 if the timezone is UTC (also in case of an exception 0 is returned - check xsink after calling)

◆ get_full_type_name()

DLLEXPORT const char* get_full_type_name ( const AbstractQoreNode * n )

returns a string type description of the full type of the value contained (ex: "nothing" for a null AbstractQoreNode pointer); differs from the return value of get_type_name() for complex types (ex: "hash<string, int>")

Since: Qore 0.8.13

◆ get_or_nothing_type_check()

DLLEXPORT const QoreTypeInfo* get_or_nothing_type_check ( const QoreTypeInfo * typeInfo )

returns the "or nothing" type for the given type

Since: Qore 0.9

◆ parse_option_bitfield_to_string_list()

DLLEXPORT QoreListNode* parse_option_bitfield_to_string_list	(	int64	i,
		ExceptionSink *	xsink
	)

returns a list<string> of parse option strings for the given bitfield; a Qore-language exception is raised for invalid values

Since: Qore 0.9

◆ parse_set_time_zone()

DLLEXPORT void parse_set_time_zone ( const char * zone )

to set the time zone from the command line

Note: this function can only be called when a program exists

◆ q_env_subst()

DLLEXPORT int q_env_subst ( QoreString & str )

performs environment variable substitution on the string argument

return 0 for OK, -1 if an error occurred (mismatched parens, etc)

Since: Qore 0.8.13

◆ q_get_thread_local_vars()

DLLEXPORT QoreHashNode* q_get_thread_local_vars	(	int	frame,

retrieves a hash of all thread local variables and their values for the given stack frame in the current thread's QoreProgram object

Parameters

frame	the stack frame starting from 0 (the current frame)
xsink	for Qore-language exceptions

Returns: a hash of local variables and their values; if the frame does not exist, an empty hash is returned; if a Qore-language exception is thrown, then nullptr is returned

Note: the current thread must be a valid Qore thread with a current QoreProgram context or the results are undefined (i.e. expect a crash)

Since: Qore 0.8.13

◆ q_gname2gid()

int q_gname2gid	(	const char *	name,
		gid_t &	gid
	)

thread-safe way to lookup a gid from a group name

Parameters

name	the group to look up
gid	the gid returned

Returns: 0 for no error, non-zero is an error code like errno

◆ q_libqore_exiting()

DLLEXPORT bool q_libqore_exiting ( )

returns true if the Qore library is exiting without a shutdown

Since: Qore 0.9.5

◆ q_libqore_initalized()

◆ q_memrmem()

DLLEXPORT void* q_memrmem	(	const void *	big,
		size_t	big_len,
		const void *	little,
		size_t	little_len
	)

finds a memory sequence in a larger memory sequence searching from the end of the sequence

Note: returns void* for compatibility with memmem() and q_memmem() signatures

Since: Qore 0.9.1

◆ q_set_thread_var_value()

DLLEXPORT int q_set_thread_var_value	(	int	frame,
		const char *	name,
		const QoreValue &	val,
		ExceptionSink *	xsink
	)

sets the value of the given thread-local variable (which may be a closure-bound variable as well) in the current stack frame for the current thread's QoreProgram object

Parameters

frame	the stack frame where 0 is the current (highest) stack frame
name	the name of the variable
val	the value to assign; the value will be referenced for the assignment if one is made
xsink	for Qore-language exceptions

Returns: 0 = OK or -1 = a Qore-language exception occurred making the assignment (ex: incompatible types) or 1 = variable not found or inaccessible stack frame (no exception thrown)

Note: pure local variables (i.e. not closure bound and not subject to the reference operator) are not stored with type information at runtime; type information is only enforced at parse / compile time, therefore it's possible to set local variables with invalid values that contradict their declarations with this function

Since: Qore 0.8.13

DLLEXPORT void qore_apply_rounding_heuristic	(	QoreString &	str,
		int	round_threshold_1,
		int	round_threshold_2
	)

finds the decimal point and attempts to remove noise and round the number if found

Parameters

str	the number string to round
round_threshold_1	the number of consecutive trailing 0 or 9 digits that will be rounded in string output
round_threshold_2	the number of consecutive trailing 0 or 9 digits that will be rounded in string output if there are trailing non-0/9 digits

Since: Qore 0.9.4

◆ qore_get_call_program_context()

DLLEXPORT QoreProgram* qore_get_call_program_context ( )

returns the caller's Program context, if any

Since: Qore 0.9

◆ qore_get_module_option()

DLLEXPORT QoreValue qore_get_module_option	(	std::string	mod,
		std::string	opt
	)

get module option for the given module

Parameters

mod	the module name
opt	the option name

Returns: the referenced option value; if a value is returned here, it must be dereferenced

Since: Qore 0.9

◆ qore_pseudo_get_class() [1/2]

DLLEXPORT const QoreClass* qore_pseudo_get_class ( qore_type_t t )

returns the pseudo-class for the given type

Since: Qore 0.9

◆ qore_pseudo_get_class() [2/2]

DLLEXPORT const QoreClass* qore_pseudo_get_class ( const QoreTypeInfo * t )

returns the pseudo-class for the given type

Since: Qore 0.9

◆ qore_reassign_signal()

DLLEXPORT QoreStringNode* qore_reassign_signal	(	int	sig,
		const char *	name
	)

allows a module to take over ownership of a signal

Parameters

sig	signal number
name	module name taking ownership of managing the signal

Returns: nullptr for OK, non-zero for failed (error message); in case a QoreStringNode pointer is returned, the caller must dereference it

See also

qore_reassign_signals() to allocate multiple signals to a module atomically
qore_release_signal() to release a signal allocation manually
qore_release_signals() to release multiple signal allocations manually

◆ qore_reassign_signals()

DLLEXPORT QoreStringNode* qore_reassign_signals	(	const sig_vec_t &	sig_vec,
		const char *	name
	)

allows a module to take over ownership of multiple signals atomically

Parameters

sig_vec	a vector of signal numbers to allocate to the module
name	module name taking ownership of managing the signal

Returns: nullptr for OK (all signals were allocated to the module), non-zero for failed (error message; no signals were allocated); in case a QoreStringNode pointer is returned, the caller must dereference it

Note: if any signal cannot be allocated to the module, no signals are allocated to the module; the call either succeeds for all or fails for all; no partial failures are possible; use this variant when allocating multiple signals to a module

See also

qore_reassign_signal() to allocate a single signal to a module
qore_release_signal() to release a signal allocation manually
qore_release_signals() to release multiple signal allocations manually

Since: Qore 0.8.13.1

◆ qore_release_signal()

DLLEXPORT int qore_release_signal	(	int	sig,
		const char *	name
	)

releases the signal allocated to the given module

Parameters

sig	the signal number allocated to the module
name	module name owning the signal

Returns: 0 = signal allocation released, -1 = no changes were made (module does not manage signal)

See also

qore_reassign_signal() to allocate a single signal to a module
qore_reassign_signals() to allocate multiple signals to a module atomically
qore_release_signals() to release multiple signal allocations manually

Since: Qore 0.8.13.1

◆ qore_release_signals()

DLLEXPORT int qore_release_signals	(	const sig_vec_t &	sig_vec,
		const char *	name
	)

releases multiple signals allocated to the given module atomically

Parameters

sig_vec	a vector of signal numbers to allocate to the module
name	module name owning the signals

Returns: 0 = signal allocations released, -1 = no changes were made (module does not manage at least one signal)

Since: Qore 0.8.13.1

◆ qore_set_module_option()

DLLEXPORT void qore_set_module_option	(	std::string	mod,
		std::string	opt,
		QoreValue	val
	)

sets a module option for the given module

Parameters

mod	the module name
opt	the option name
val	the option value; must be already referenced for the assignment

Since: Qore 0.9
