StdGUI User Data Functions |

int set_userdata(TARGET *p_tgt, char *p_name, void *p_data); int get_userdata(TARGET *p_tgt, char *p_name, void **p_data); int delete_userdata(TARGET *p_tgt, char *p_name); int index_userdata(TARGET *p_tgt, int p_index, char **p_name, void **p_data); |
|
The set_userdata() function assigns a user-supplied data value (actually a void pointer) to a named slot on a window, widget or application context. The get_userdata() function returns a named user data value from a window, widget or application context. The delete_userdata() function removes a named user data value from a window, widget or application context. The index_userdata() function returns information about user data values on a window, widget or application context. Each user data item is indexed by a simple integer and the data item name and value are returned in the p_name and p_data parameters. |
|
All four functions return zero (0) on success, non-zero on failure. |
