typedef struct { GvaMameCallback callback; gpointer user_data; } GvaMameAsyncData;
This structure is used to pass callback information to asynchronous operations.

GvaMameAsyncData * gva_mame_async_data_new (GvaMameCallback callback, gpointer user_data);
Creates a new GvaMameAsyncData structure and populates it with callback
and user_data
. Call gva_mame_async_data_free()
to free it.

Returns : |
a new GvaMameAsyncData |

gint gva_mame_command (const gchar *arguments, gchar ***stdout_lines, gchar ***stderr_lines, GError **error);
Spawns MAME with arguments
and blocks until the child process exits.
The line-based output from the stdout and stderr pipes are written to
stdout_lines
and stderr_lines
, respectively, as NULL
-terminated
string arrays. The function returns the exit status of the child
process, or -1 if an error occurred while spawning the process.
|
command line arguments |
|
return location for stdout lines, or NULL
|
|
return location for stderr lines, or NULL
|
|
return locations for a GError, or NULL
|
Returns : |
exit status of the child process or -1 if an error occurred |
