- SYNOPSIS
- #include <string.h>
-
- char *strchr(char const *s, int c);
-
- char *strrchr(char const *s, int c);
-
- DESCRIPTION
- 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.
-
- Here "character" means "byte" - these functions do not work with wide
- or multi-byte characters.
-
- RETURN VALUE
- The strchr() and strrchr() functions return a pointer to the matched
- character or NULL if the character is not found.
-
