Detailed Description

Option constants

Variable Documentation

const Qore::Option::HAVE_ATOMIC_OPERATIONS = bool(QORE_CONST_HAVE_ATOMIC_MACROS)

Indicates if the Qore library supports fast atomic reference counting.

Note that if this constant is False, atomic operations are supported by mutexes and are therefore slower than with native atomic reference counting operations

const Qore::Option::HAVE_FILE_LOCKING = bool(QORE_CONST_HAVE_STRUCT_FLOCK)

Indicates if the Qore library supports file locking; currently this depends on UNIX-style file locking with the fnctl() function.

Note

Currently this function is only available when running on UNIX or UNIX-like platforms

const Qore::Option::HAVE_FORK = bool(QORE_CONST_HAVE_FORK)

Indicates if the fork() function is available.

Note

This constant is always False on native Windows ports

const Qore::Option::HAVE_GETPPID = bool(QORE_CONST_HAVE_GETPPID)

Indicates if the getppid() function is available.

Note

This constant is always False on native Windows ports

const Qore::Option::HAVE_IS_EXECUTABLE = bool(QORE_CONST_HAVE_PWD_H)

Indicates if the Qore library supports the is_executable() function.

Note

Currently this function is only available when running on UNIX or UNIX-like platforms

const Qore::Option::HAVE_KILL = bool(QORE_CONST_HAVE_KILL)

Indicates if the kill() function is available.

Note

This constant is always False on native Windows ports

const Qore::Option::HAVE_SETEGID = bool(QORE_CONST_HAVE_SETEGID)

Indicates if the setegid() function is available; the availabilty of this function depends on the system's underlying C-library.

Note

This constant is always False on native Windows ports

const Qore::Option::HAVE_SETEUID = bool(QORE_CONST_HAVE_SETEUID)

Indicates if the seteuid() function is available; the availabilty of this function depends on the system's underlying C-library.

Note

This constant is always False on native Windows ports

const Qore::Option::HAVE_SETSID = bool(QORE_CONST_HAVE_SETSID)

Indicates if the setsid() function is available.

Note

This constant is always False on native Windows ports

const Qore::Option::HAVE_SIGNAL_HANDLING = qore(get_bool_node(QORE_CONST_HAVE_SIGNAL_HANDLING && !(qore_library_options & QLO_DISABLE_SIGNAL_HANDLING)))

Indicates if UNIX-style signal handling is available.

If this constant is False, then the set_signal_handler() and remove_signal_handler() functions are not available.

Note

This constant is always False on native Windows ports and is also False if the qore library was initialized with signals disabled (such as with qore -b or qore –disable-signals)

Signal Handling

const Qore::Option::HAVE_STATVFS = bool(QORE_CONST_HAVE_SYS_STATVFS_H)

Indicates if the statvfs() function is available.

Note

This constant is always False on native Windows ports

const Qore::Option::HAVE_SYMLINK = bool(QORE_CONST_HAVE_SYMLINK)

Indicates if the symlink() function is available.

Note

This constant is always False on native Windows ports

Since

Qore 0.8.6 although the symlink() function was added in 0.8.5

const Qore::Option::HAVE_TERMIOS = bool(QORE_CONST_HAVE_TERMIOS_H)

Indicates if the TermIOS class is available.

Note

This constant is always False on native Windows ports

const Qore::Option::HAVE_UNIX_FILEMGT = bool(QORE_CONST_HAVE_CHOWN)

Indicates if UNIX-style file management functionality is available (ex: chown(), Dir::chgrp(), etc)

Note

This constant is always False on native Windows ports

const Qore::Option::HAVE_UNIX_USERMGT = bool(QORE_CONST_HAVE_GETUID)

Indicates if UNIX-style user management functionality is available (ex: getuid(), setuid(), getgid(), setgid(), etc)

Note

This constant is always False on native Windows ports
