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++.
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; } |
