SDL_OUT_Z_CAP - Macro that annotates function params with output string buffer size.
Contents
Availability
This macro is available since SDL 3.2.0.
Simple Directmedia Layer SDL 3.2.10 SDL_OUT_Z_CAP(3)
Description
If we were to annotate snprintf :
int snprintf(SDL_OUT_Z_CAP(maxlen) char *text, size_t maxlen, const char *fmt, ...);
This notes that text is a null-terminated C string, should be maxlen bytes in size, and is only written
to by the function. The compiler or other analysis tools can warn when this doesn't appear to be the
case.
On compilers without this annotation mechanism, this is defined to nothing.
