    1.18 +* FUNCTION
    1.19 +* <<strpbrk>>---find chars in string
    1.20 +* INDEX
    1.21 +* strpbrk
    1.22 +* ANSI_SYNOPSIS
    1.23 +* #include <string.h>
    1.24 +* char *strpbrk(const char *<[s1]>, const char *<[s2]>);
    1.25 +* TRAD_SYNOPSIS
    1.26 +* #include <string.h>
    1.27 +* char *strpbrk(<[s1]>, <[s2]>)
    1.28 +* char *<[s1]>;
    1.29 +* char *<[s2]>;
    1.30 +* This function locates the first occurence in the string
    1.31 +* pointed to by <[s1]> of any character in string pointed to by
    1.32 +* <[s2]> (excluding the terminating null character).
    1.33 +* RETURNS
    1.34 +* <<strpbrk>> returns a pointer to the character found in <[s1]>, or a
    1.35 +* null pointer if no character from <[s2]> occurs in <[s1]>.
    1.36 +* PORTABILITY
    1.37 +* <<strpbrk>> requires no supporting OS subroutines.

    1.47 +Scan string for specified characters.
