Description [src]
A wrapper around g_spawn_async_with_pipes() with async-signal-safe
implementation of GSpawnChildSetupFunc to launch a child program
asynchronously resetting the rlimit nofile on child setup.
Parameters
working_directory-
Type:
const char*Child’s current working directory, or
NULLto inherit parent’s.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
char*child's argument vector.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
char*child's environment, or `NULL` to inherit parent's.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. standard_input-
Type:
int*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-
Type:
int*Return location for file descriptor to read child’s stdout, or
NULL.The argument will be set by the function. The argument can be NULL. standard_error-
Type:
int*Return location for file descriptor to read child’s stderr, or
NULL.The argument will be set by the function. The argument can be NULL. 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.
Return value
Type: GPid
The PID of the child on success, 0 if error is set.
