DESCRIPTION
The
strrchr()
function locates the last occurrence of the character
c (converted to a char) in the string
s. The terminating NUL character is considered part of
the string. If c is
‘\0’,
strrchr() locates the terminating
‘\0’.
The
rindex()
function is an old synonym for strrchr().
RETURN VALUES
The strrchr() function returns a pointer
to the located character or NULL if the character
does not appear in the string.
EXAMPLES
After the following call to strrchr(),
p will point to the string "obar":
char *p; char *s = "foobar"; p = strrchr(s, 'o');
