since: 2.58
Declaration
gboolean
g_spawn_async_with_fds (
const gchar* working_directory,
gchar** argv,
gchar** envp,
GSpawnFlags flags,
GSpawnChildSetupFunc child_setup,
gpointer user_data,
GPid* child_pid,
gint stdin_fd,
gint stdout_fd,
gint stderr_fd,
GError** error
)
Description
Executes a child program asynchronously.
Identical to g_spawn_async_with_pipes_and_fds() but with n_fds set to zero,
so no FD assignments are used.
Available since: 2.58
Parameters
working_directory-
Type:
const gchar*Child’s current working directory, or
NULLto inherit parent’s, in the GLib file name encoding.The argument can be NULL.The data is owned by the caller of the function. The value is a platform-native string, using the preferred OS encoding on Unix and UTF-8 on Windows. argv-
Type: An array of
gchar*Child’s argument vector, in the GLib file name encoding; it must be non-empty and
NULL-terminated.The array must be NULL-terminated.The data is owned by the caller of the function. Each element is a NUL terminated UTF-8 string. envp-
Type: An array of
gchar*Child’s environment, or
NULLto inherit parent’s, in the GLib file name encoding.The argument can be NULL.The array must be NULL-terminated.The data is owned by the caller of the function. Each element is a NUL terminated UTF-8 string. flags-
Type:
GSpawnFlagsFlags from
GSpawnFlags. child_setup-
Type:
GSpawnChildSetupFuncFunction to run in the child just before
exec().The argument can be NULL. user_data-
Type:
gpointerUser data for
child_setup.The argument can be NULL.The data is owned by the caller of the function. child_pid-
Type:
GPidReturn location for child process ID, or
NULL.The argument will be set by the function. The argument can be NULL.The caller of the function takes ownership of the returned data, and is responsible for freeing it. stdin_fd-
Type:
gintFile descriptor to use for child’s stdin, or
-1. stdout_fd-
Type:
gintFile descriptor to use for child’s stdout, or
-1. stderr_fd-
Type:
gintFile descriptor to use for child’s stderr, or
-1. 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.
