strchr
Locates the first occurrence of a specified character in a string (function or macro)
#include <string.h>
char *strchr (
const char *s,
int c);
strchr returns a pointer to the located character, or NULL if the character does not occur in the string.
The strchr function or macro locates the first occurrence of c (converted to a char) in the string pointed to by s. The terminating NULL character is considered to be part of the string.

strcpy (buffer, "01234ABCD");
where = strchr (buffer, ’x’);
if (where == NULL)
{

}
