Description
The routine
PA_UsePStrings
tells the API to send/receive Pascal strings in every call that use strings.
NOTE FOR Macintosh DEVELOPERS
By default, C strings are used when compiling for MacOS, since all the API uses the type char * for strings, instead of unsigned char *. Using C strings by default avoids typecasting when calling the API's routines. In order to call Macintosh traps using the Str255 type, you should call
PA_UsePStrings
when necessary or use it before calls to Macintosh traps, and then restore strings by calling
PA_UseCStrings
.
