strchr, strrchr, strchrnul − locate character in string
#include <string.h>
char *strchr(const char *s, int c);
char *strrchr(const char *s, int c);
#define
_GNU_SOURCE
#include <string.h>
char *strchrnul(const char *s, int c);
The strchr() function returns a pointer to the first occurrence of the character c in the string s.
The strrchr() function returns a pointer to the last occurrence of the character c in the string s.
The strchrnul() function is like strchr() except that if c is not found in s, then it returns a pointer to the null byte at the end of s, rather than NULL.
Here "character" means "byte"; these functions do not work with wide or multi-byte characters.
The strchr() and strrchr() functions return a pointer to the matched character or NULL if the character is not found.
The strchrnul() function returns a pointer to the matched character, or a pointer to the null byte at the end of s (i.e., s+strlen(s)) if the character is not found.
