Description

Identical to g_spawn_async_with_pipes_and_fds() but with n_fds set to zero, so no FD assignments are used.

Parameters

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 file system path, using the OS encoding.
flags

Type: GSpawnFlags

Flags from GSpawnFlags.

child_setup

Type: GSpawnChildSetupFunc

Function to run in the child just before exec()

The argument can be NULL.
user_data

Type: gpointer

User data for child_setup.

The argument can be NULL.
The data is owned by the caller of the function.
child_pid

Type: GPid

Return location for child process ID, or NULL.

The argument will be set by the function.
The argument can be NULL.
The called function takes ownership of the data, and is responsible for freeing it.
standard_input

Type: gint*

Return location for file descriptor to write to child’s stdin, or NULL.

The argument will be set by the function.
The argument can be NULL.
standard_output
