I found a bug. I was missing '_' in identifier names. So it didn't
match memcpy(3), which uses size_t. Also, I found some spurious match,
so added a '$' anchor after the ';'.
stdc89()
{
grep "[[:alpha:]] \**\b$1([[:alnum:]*,._ ]*);" /path/to/c89-draft.txt \
| sort \
| uniq;
}
This function finds 136 declarations in C89. I'm not sure if that's
all of them. Is anyone missing any?
Cheers,
Alex
