    1.18 +* FUNCTION
    1.19 +* <<strrchr>>---reverse search for character in string
    1.20 +* INDEX
    1.21 +* strrchr
    1.22 +* ANSI_SYNOPSIS
    1.23 +* #include <string.h>
    1.24 +* char * strrchr(const char *<[string]>, int <[c]>);
    1.25 +* TRAD_SYNOPSIS
    1.26 +* #include <string.h>
    1.27 +* char * strrchr(<[string]>, <[c]>);
    1.28 +* char *<[string]>;
    1.29 +* int *<[c]>;
    1.30 +* This function finds the last occurence of <[c]> (converted to
    1.31 +* a char) in the string pointed to by <[string]> (including the
    1.32 +* terminating null character).
    1.33 +* RETURNS
    1.34 +* Returns a pointer to the located character, or a null pointer
    1.35 +* if <[c]> does not occur in <[string]>.
    1.36 +* PORTABILITY
    1.37 +* <<strrchr>> is ANSI C.
    1.38 +* <<strrchr>> requires no supporting OS subroutines.

    1.51 +Returns the last occurrence of c in string.
    1.52 +The null-terminating character is included as part of the string and can also be searched.
    1.53 +@return If character is found, a pointer to the last occurrence of c in string is returned.
    1.54 +If not, NULL is returned.
    1.55 +@param s Null-terminated string scanned in the search.
