Hi. Just wanted to share that the following macro gives an error on latest
versions of GCC, but is reported to work on 2.95.3 (tested on MorphOS but
should be the same for other OSses of course).
Both an old version of SASC(AmigaOS) and Borland (on X86) worked fine.
#include<stdio.h>
#define EXTRACTBRCKTELMNT(Terminator, Elmnt) #Elmnt, #Terminator
#define GETBRCKTELMNT(ToExtract)
GETELMNTEXPAND(EXTRACTBRCKTELMNT##ToExtract)
#define GETELMNTEXPAND(a) GETELMNTEXPAND2 (a)
#define GETELMNTEXPAND2(a, b) a, b
int main (int argc, char **argv)
{ printf("%s %s\n", GETBRCKTELMNT((YYY, XXX)));
getchar();
return (0);
}
Regs
Jose
