in strspn(): what "spn" stands for?

[Tim Prince]

span?

span was a Cobol verb, which had useful hardware support in certain
instruction sets. I used it in a string data processing library called
from Fortran 66, before C or f77 compilers were available.

Why don't you read the documentation (or source) from whomever supplied
you that (non-standard) function?

strspn was part of the original C standard, and is part of the current C
standard. <OT> And if you have trouble understanding when "whom" is
appropriate, please just avoid it, at least until you figure it out.
