The child will inherit the parent's standard error.

the child will inherit the parent's standard input (by default, the child's standard input is attached to /dev/null).

The child will inherit the parent's standard output.

create all pipes with the O_CLOEXEC flag set. Since: 2.40

no flags, default behaviour

the child will not be automatically reaped; you must use g_child_watch_add() yourself (or call waitpid() or handle SIGCHLD yourself), or the child will become a zombie.

the first element of argv is the file to execute, while the remaining elements are the actual argument vector to pass to the file. Normally g_spawn_async_with_pipes() uses argv[0] as the file to execute, and passes all of argv to the child.

the parent's open file descriptors will be inherited by the child; otherwise all descriptors except stdin, stdout and stderr will be closed before calling exec() in the child.

argv[0] need not be an absolute path, it will be looked for in the user's PATH.

if argv[0] is not an absolute path, it will be looked for in the PATH from the passed child environment. Since: 2.34

the child's standard error will be discarded.

The child's standard input is attached to /dev/null.

the child's standard output will be discarded, instead of going to the same location as the parent's standard output.
