FUNCTION
|
|
<<strpbrk>>---find characters in string
|
|
|
|
INDEX
|
|
strpbrk
|
|
|
|
ANSI_SYNOPSIS
|
|
#include <string.h>
|
|
char *strpbrk(const char *<[s1]>, const char *<[s2]>);
|
|
|
|
TRAD_SYNOPSIS
|
|
#include <string.h>
|
|
char *strpbrk(<[s1]>, <[s2]>)
|
|
char *<[s1]>;
|
|
char *<[s2]>;
|
|
|
|
DESCRIPTION
|
|
This function locates the first occurence in the string
|
|
pointed to by <[s1]> of any character in string pointed to by
|
|
<[s2]> (excluding the terminating null character).
|
|
|
|
RETURNS
|
|
<<strpbrk>> returns a pointer to the character found in <[s1]>, or a
|
|
null pointer if no character from <[s2]> occurs in <[s1]>.
|
|
|
|
PORTABILITY
|
|
<<strpbrk>> requires no supporting OS subroutines.
