Static functions

errorQuark

GQuark errorQuark()

fdAdd

uint fdAdd(int fd, GIOCondition condition, GUnixFDSourceFunc function_, void* userData)

Sets a function to be called when the IO condition, as specified by @condition becomes true for @fd.

fdAddFull

uint fdAddFull(int priority, int fd, GIOCondition condition, GUnixFDSourceFunc function_, void* userData, GDestroyNotify notify)

Sets a function to be called when the IO condition, as specified by @condition becomes true for @fd.

fdSourceNew

Source fdSourceNew(int fd, GIOCondition condition)

Creates a #GSource to watch for a particular IO condition on a file descriptor.

openPipe

bool openPipe(int* fds, int flags)

Similar to the UNIX pipe() call, but on modern systems like Linux uses the pipe2() system call, which atomically creates a pipe with the configured flags. The only supported flag currently is %FD_CLOEXEC. If for example you want to configure %O_NONBLOCK, that must still be done separately with fcntl().

setFdNonblocking

bool setFdNonblocking(int fd, bool nonblock)

Control the non-blocking state of the given file descriptor, according to @nonblock. On most systems this uses %O_NONBLOCK, but on some older ones may use %O_NDELAY.

signalAdd

uint signalAdd(int signum, GSourceFunc handler, void* userData)

A convenience function for g_unix_signal_source_new(), which attaches to the default #GMainContext. You can remove the watch using g_source_remove().

signalAddFull

uint signalAddFull(int priority, int signum, GSourceFunc handler, void* userData, GDestroyNotify notify)

A convenience function for g_unix_signal_source_new(), which attaches to the default #GMainContext. You can remove the watch using g_source_remove().

signalSourceNew

Source signalSourceNew(int signum)

Create a #GSource that will be dispatched upon delivery of the UNIX signal @signum. In GLib versions before 2.36, only SIGHUP, SIGINT, SIGTERM can be monitored. In GLib 2.36, SIGUSR1 and SIGUSR2 were added. In GLib 2.54, SIGWINCH was added.
