strchr

The strchr function scans a string for the first occurrence of a given character.

str_ptr

points to the string to scan.

chr

is the character to scan for.

Return Value

points to the first occurrence in *str_ptr of chr. If *str_ptr does not contain chr, then

strchr returns the pointer value NULL.

Example

This example searches string s for the character “a” and prints the character:

#include <stringh>

#include <stdioh>

int main(void)

{

char *p;

char *s;

int c;

c = 'a';

s = "This is an example";

p = strchr(s, c);

printf("%c", *p);

}

#include <stringh>

char *strchr(const char *str_ptr, int chr);
