Ptr

Ptr data type

#include <Types.h>

typedef char * Ptr; /* generic pointer to a signed byte */

Notes: All pointers in Macintosh programming are 32-bit values. A Ptr is

generally used in cases where the data type is unknown or as a quasi-"void",

which you will need to coerce into a standard data type. Nearly all

system- defined data structures have a specific name typedef'd for

programming convenience.

A Handle is a pointer to a pointer to a signed byte. A StringPtr is a pointer

to an unsigned byte.

See Byte for descriptions of pString (Pascal string) and ASCIIZ (C- string).
