Function
GLibUnixPipeclose
since: 2.80
Declaration [src]
gboolean
g_unix_pipe_close (
GUnixPipe* self,
GUnixPipeEnd end,
GError** error
)
Description [src]
Close one of the ends of the pipe and set the relevant member of fds
to -1 before returning, equivalent to g_clear_fd().
Like g_close(), if closing the file descriptor fails, the error is
stored in both %errno and error. If this function succeeds,
%errno is undefined.
This function is async-signal safe if error is NULL and the relevant
member of fds is either negative or a valid open file descriptor.
This makes it safe to call from a signal handler or a GSpawnChildSetupFunc
under those conditions.
See signal(7) and
signal-safety(7) for more details.
To close both file descriptors and ignore any errors, use
g_unix_pipe_clear() instead.
Available since: 2.80
This function is not directly available to language bindings.
Parameters
self-
Type:
GUnixPipeA pair of file descriptors.
The data is owned by the caller of the function. end-
Type:
GUnixPipeEndOne of the ends of the pipe.
error-
Type:
GError **The return location for a recoverable error.
The argument can be NULL.If the return location is not NULL, then you must initialize it to aNULLGError*.The argument will be left initialized to NULLby the function if there are no errors.In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.
