strrchr: locate character in string
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 /* See feature_test_macros(7) */ #include <string.h> char *strchrnul(const char *s, int c);
DESCRIPTIONThe 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.
RETURN VALUEThe strchr() and strrchr() functions return a pointer to the matched character or NULL if the character is not found. The terminating null byte is considered part of the string, so that if c is specified as '\0', these functions return a pointer to the terminator.
VERSIONSstrchrnul() first appeared in glibc in version 2.1.1.
