I suppose the motivation is performance?
If so, have you measured the improvement?
Actually, no, it is not for performance. I found it wearisome to write:
if (isalnum(x) || (x == '_') || (x == '.......
all over the place. I saw what Zack W. was doing in CPP and decided there
had to be a way to specify the classifications, spit out a table and
not fret over it any more. (I did a first incantation a decade ago.)
So, if there is a performance improvement, it would be amusing to know what
it might be. I haven't measured tho. If ctype.h completely satisfies your
need, I'm sure there is little to no improvement (other than for
strspn and strpbrk -- there is no reverse spanning or breaking).
