A pointer isn't a magical type that knows what you want it to do. It's just a numerical type with extra operators, = still means=. Ergo, when you use = on it, you're telling it to point to a completely different spot in memory. If you want to preserve memory you already have, you have to use string operations or array operations to copy it in.

XmRepTypeGetRegistered(library call)									      XmRepTypeGetRegistered(library call)

NAME
XmRepTypeGetRegistered -- A representation type manager function that returns a copy of the registration list SYNOPSIS
#include <Xm/RepType.h> XmRepTypeList XmRepTypeGetRegistered(void) DESCRIPTION
XmRepTypeGetRegistered retrieves information about all representation types that are registered with the representation type manager. The registration list is an array of structures, each of which contains information for a representation type entry. The end of the registra- tion list is marked with a representation type entry whose rep_type_name field has a NULL pointer. This routine allocates memory for the returned data. The application must free this memory using XtFree. The representation type entry structure contains the following information: typedef struct { String rep_type_name; String *value_names; unsigned char *values; unsigned char num_values; Boolean reverse_installed; XmRepTypeId rep_type_id; } XmRepTypeEntryRec, *XmRepTypeList; (void) rep_type_name The name of the representation type value_names An array of representation type value names values An array of representation type numerical values num_values The number of values associated with the representation type reverse_installed A flag that indicates whether or not the reverse converter is installed rep_type_id The identification number of the representation type RETURN
Returns a pointer to the registration list of representation types. RELATED
