Declaration [src]

static inline int
g_unix_pipe_steal (
  GUnixPipe* self,
  GUnixPipeEnd end
)

Description [src]

Return one of the ends of the pipe. It becomes owned by the caller, and the file descriptor in the data structure is set to -1, similar to g_steal_fd().

This function is async-signal safe (see signal(7) and signal-safety(7)), making it safe to call from a signal handler or a GSpawnChildSetupFunc.

This function preserves the value of errno.

Available since: 2.80

This method is not directly available to language bindings.

Parameters

end

Type: GUnixPipeEnd

One of the ends of the pipe.

Return value

Type: int

A non-negative file descriptor, which becomes owned by the caller and must be closed by the caller if required, or a negative number if the corresponding end of the pipe was already closed or stolen.
