Function

GLibspawn_command_line_sync

Declaration

gboolean
g_spawn_command_line_sync (
  const gchar* command_line,
  gchar** standard_output,
  gchar** standard_error,
  gint* wait_status,
  GError** error
)

Description

A simple version of g_spawn_sync() with little-used parameters removed, taking a command line instead of an argument vector.

See g_spawn_sync() for full details.

The command_line argument will be parsed by g_shell_parse_argv().

Unlike g_spawn_sync(), the G_SPAWN_SEARCH_PATH flag is enabled. Note that G_SPAWN_SEARCH_PATH can have security implications, so consider using g_spawn_sync() directly if appropriate.

Possible errors are those from g_spawn_sync() and those from g_shell_parse_argv().

If wait_status is non-NULL, the platform-specific status of the child is stored there; see the documentation of g_spawn_check_wait_status() for how to use and interpret this. On Unix platforms, note that it is usually not equal to the integer passed to exit() or returned from main().

On Windows, please note the implications of g_shell_parse_argv() parsing command_line. Parsing is done according to Unix shell rules, not Windows command interpreter rules. Space is a separator, and backslashes are special. Thus you cannot simply pass a command_line containing canonical Windows paths, like “c:\program files\app\app.exe”, as the backslashes will be eaten, and the space will act as a separator. You need to enclose such paths with single quotes, like “‘c:\program files\app\app.exe’ ‘e:\folder\argument.txt’”.

Parameters

command_line const gchar*
 

A command line.

 The data is owned by the caller of the function.
 The string is a file system path, using the OS encoding.
standard_output An array of guint8
 

Return location for child output.

 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_error An array of guint8
 

Return location for child errors.

 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.
wait_status gint*
 

Return location for child wait status, as returned by waitpid()

 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.
error GError **
  The return location for a GError*, or NULL.

Return value

Returns: gboolean
 

TRUE on success, FALSE if an error was set.
