Function Documentation
| int gs_comp_dsi_object | ( | void * | key, | |
| void * | d | |||
| ) |
Comparison function for DSI objects.
- Parameters:
-
key -- arg pointer to be compared d -- arg pointer to be compared
- Returns:
- 0 if equal, non-zero otherwise.
Definition at line 31 of file dsi_storage.c.
{
return (key != d);
}
Here is the caller graph for this function:
| void gs_free_dsi_object | ( | void * | d | ) |
Frees a DSI object.
- Parameters:
-
d -- pointer to object to be freed.
Definition at line 43 of file dsi_storage.c.
{
free(d);
}
Here is the caller graph for this function:
| int gs_insert_dsi_object | ( | DSI_OBJECT * | dsi_obj | ) |
Inserts the object into the list of DSI objects.
- Parameters:
-
dsi_obj -- object to be inserted.
- Returns:
- 0 on success, -1 on failure.

Here is the caller graph for this function:
| int gs_is_dsi_object | ( | void * | obj | ) |
Determines whether the specified pointer is a DSI object or just a regular argument.
- Parameters:
-
obj -- pointer to the argument to check
- Returns:
- 1 if it is a DSI object, 0 otherwise.
