Function

GLibunix_open_pipe

Declaration

gboolean
g_unix_open_pipe (
  gint* fds,
  gint flags,
  GError** error
)

Description

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().

This function does not take O_CLOEXEC, it takes FD_CLOEXEC as if for fcntl(); these are different on Linux/glibc.

Available since:

2.30

Parameters

`fds`	`gint*`
	Array of two integers.
	The data is owned by the caller of the function.
`flags`	`gint`
	Bitfield of file descriptor flags, as for `fcntl()`
`error`	`GError **`
	The return location for a `GError*`, or `NULL`.

Return value

Returns:	`gboolean`
	`TRUE` on success, `FALSE` if not (and errno will be set).
