Unix-specific Utilities

Most of GLib is intended to be portable; in contrast, this set of functions is designed for programs which explicitly target Unix, or are using it to build higher level abstractions which would be conditionally compiled if the platform matches G_OS_UNIX.

To use these functions, you must explicitly include the glib-unix.h header.

File Descriptors

• g_unix_open_pipe()
• g_unix_set_fd_nonblocking()

Pipes

The GUnixPipe structure can be used to conveniently open and manipulate a Unix pipe.

The methods for it are all static inline for efficiency. They are:

• g_unix_pipe_open()
• g_unix_pipe_get()
• g_unix_pipe_steal()
• g_unix_pipe_close()
• g_unix_pipe_clear()

Signals

• g_unix_signal_add()
• g_unix_signal_add_full()
• g_unix_signal_source_new()

Polling

• g_unix_fd_add()
• g_unix_fd_add_full()
• g_unix_fd_source_new()

User Database

• g_unix_get_passwd_entry()
