PtGetStruct()

Retrieve the specified resource

Synopsis:

int PtGetStruct( char *base, 
                 PtResourceRec_t const *mod, 
                 PtArg_t *arg );

Description:

This function retrieves the resource specified by arg from the widget at address base as described by mod.

If the value and len members of arg are non-NULL, they're assumed to contain the addresses of pointers of the type appropriate for the resource. The pointers are set to point to the resource's value in the widget's internal memory.

Don't use these pointers to change the resource's value.

If either of the value and len members of arg is NULL, the retrieved resources are stored in these members.

Returns:

0

Successful completion.
