56a424cca6b3f91f31bdab72a4626c48c779fe8bmp * Function: nstrtok
56a424cca6b3f91f31bdab72a4626c48c779fe8bmp * Purpose: the same as strtok ... just different. does not deal with
56a424cca6b3f91f31bdab72a4626c48c779fe8bmp * multiple tokens in row.
56a424cca6b3f91f31bdab72a4626c48c779fe8bmp * Arguments:
56a424cca6b3f91f31bdab72a4626c48c779fe8bmp * s (input) string to scan
56a424cca6b3f91f31bdab72a4626c48c779fe8bmp * delim (input) list of delimiters
56a424cca6b3f91f31bdab72a4626c48c779fe8bmp * <return value> string or null on error.
56a424cca6b3f91f31bdab72a4626c48c779fe8bmp * Requires:
56a424cca6b3f91f31bdab72a4626c48c779fe8bmp * Effects:
56a424cca6b3f91f31bdab72a4626c48c779fe8bmp * sets last to string
56a424cca6b3f91f31bdab72a4626c48c779fe8bmp * Modifies:
56a424cca6b3f91f31bdab72a4626c48c779fe8bmp register char *s;
56a424cca6b3f91f31bdab72a4626c48c779fe8bmp register const char *delim;
56a424cca6b3f91f31bdab72a4626c48c779fe8bmp * Skip (span) leading delimiters (s += strspn(s, delim), sort of).
56a424cca6b3f91f31bdab72a4626c48c779fe8bmp if (c == sc)

56a424cca6b3f91f31bdab72a4626c48c779fe8bmp * Scan token (scan for delimiters: s += strcspn(s, delim), sort of).
56a424cca6b3f91f31bdab72a4626c48c779fe8bmp * Note that delim must have one NUL; we stop if we see that, too.
