Struct

GLibUnixPipe

since: 2.80

Description [src]

struct GUnixPipe {
  None fds;
}

A Unix pipe. The advantage of this type over int[2] is that it can be closed automatically when it goes out of scope, using g_auto(GUnixPipe), on compilers that support that feature.

Structure members

fds: A pair of file descriptors, each negative if closed or not yet opened. The file descriptor with index G_UNIX_PIPE_END_READ is readable. The file descriptor with index G_UNIX_PIPE_END_WRITE is writable.

Available since: 2.80

Functions

g_unix_pipe_clear

Close both ends of the pipe, unless they have already been closed or stolen. Any errors are ignored: use g_unix_pipe_close() or g_clear_fd() if error-handling is required.

since: 2.80

g_unix_pipe_close

Close one of the ends of the pipe and set the relevant member of fds to -1 before returning, equivalent to g_clear_fd().

since: 2.80

g_unix_pipe_get

Return one of the ends of the pipe. It remains owned by self.

since: 2.80

g_unix_pipe_open

Open a pipe. This is the same as g_unix_open_pipe(), but uses the GUnixPipe data structure.

since: 2.80

g_unix_pipe_steal

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().
