Locate character in string
Usage

Library
Standard C Library (libc, -lc)
Overview
The strchr() function locates the first occurrence of c (converted to a char) in the string pointed to by s. The terminating null character is considered part of the string; therefore if c is ‘\0’, the functions locate the terminating ‘\0’.
The strrchr() function is identical to strchr() except it locates the last occurrence of c.
The strchrnul() function is identical to strchr() except that if c is not found in s a pointer to the terminating ‘\0’ is returned.
Return values
The functions strchr() and strrchr() return a pointer to the located character, or NULL if the character does not appear in the string.
strchrnul() returns a pointer to the terminating ‘\0’ if the character does not appear in the string.
