strpbrk


function
<cstring>
const char * strpbrk ( const char * str1, const char * str2 );
      char * strpbrk (       char * str1, const char * str2 );

Locate character in string

Returns a pointer to the first occurrence in str1 of any of the characters that are part of str2, or a null pointer if there are no matches.

The search does not include the terminating null-characters.

Parameters

str1
C string to be scanned.
str2
C string containing the characters to match.


Return Value

A pointer to the first occurrence in str1 of any of the characters that are part of str2, or a null pointer if none of the characters of str2 is found in str1 before the terminating null-character.
If none of the characters of str2 is present in str1, a null pointer is returned.

Portability

In C, this function is declared as:

char * strpbrk ( const char *, const char * );

instead of the two overloaded versions provided in C++.
