 strpbrk(const char* string1, const char* string2)

Defined in string.h.

Scan string for specified characters.

Scans string1 character by character, returning a pointer to the first character that matches with any of the characters in string2. The search does not includes the terminating null-characters.

Syntax

char *strpbrk ( const char *string1, const char *string2)

Parameters

• string1
  Null-terminated string to be scanned.
• string2
  Null-terminated string containing the character set to search for.

Return Value

A pointer to the first appearance in string1 of a character specified in string2.

If none of the characters specified in string2 exists in string1, a NULL pointer is returned.

Portability.

Defined in ANSI-C.

ANSI-C++ standard specifies two different declarations for this function instead of the one included in ANSI-C:

const char* strpbrk(const char* string1, const char* string2); char* strpbrk(char* string1, const char* string2);

Both have the same behavior as the original declaration.

Example.

/* strpbrk example */
#include <stdio.h>
#include <string.h>

int main ()
{
  char str[] = "This is a sample string";
  char key[] = "aeiou";
  char * pch;
  printf ("Vowels in '%s': ",str);
  pch = strpbrk (str, key);
  while (pch != NULL)
  {
    printf ("%c " , *pch);
    pch = strpbrk (pch+1,key);
  }
  printf ("\n");
  return 0;
}

Output:
Vowels in 'This is a sample string': i i a a e i
