GSubprocessFlags

Flags to define the behaviour of a #GSubprocess.

Note that the default for stdin is to redirect from /dev/null. For stdout and stderr the default are for them to inherit the corresponding descriptor from the calling process.

Note that it is a programmer error to mix 'incompatible' flags. For example, you may not request both %G_SUBPROCESS_FLAGS_STDOUT_PIPE and %G_SUBPROCESS_FLAGS_STDOUT_SILENCE.

Values

ValueMeaning
NONE0

No flags.

STDIN_PIPE1

create a pipe for the stdin of the spawned process that can be accessed with g_subprocess_get_stdin_pipe().

STDIN_INHERIT2

stdin is inherited from the calling process.

STDOUT_PIPE4

create a pipe for the stdout of the spawned process that can be accessed with g_subprocess_get_stdout_pipe().

STDOUT_SILENCE8

silence the stdout of the spawned process (ie: redirect to /dev/null).

STDERR_PIPE16

create a pipe for the stderr of the spawned process that can be accessed with g_subprocess_get_stderr_pipe().

STDERR_SILENCE32

silence the stderr of the spawned process (ie: redirect to /dev/null).

STDERR_MERGE64

merge the stderr of the spawned process with whatever the stdout happens to be. This is a good way of directing both streams to a common log file, for example.

INHERIT_FDS128

spawned processes will inherit the file descriptors of their parent, unless those descriptors have been explicitly marked as close-on-exec. This flag has no effect over the "standard" file descriptors (stdin, stdout, stderr).
