.Sh NAME
.Nm strchr , strrchr
.Nd locate character in string
.Sh LIBRARY
.Lb libc
.Sh SYNOPSIS
.In string.h
.Ft "char *"
.Fn strchr "const char *s" "int c"
.Ft "char *"
.Fn strrchr "const char *s" "int c"
.Sh DESCRIPTION
The
.Fn strchr
function locates the first occurrence of
.Fa c
(converted to a
.Vt char )
in the string pointed to by
.Fa s .
The terminating null character is considered part of the string;
therefore if
.Fa c
is
.Ql \e0 ,
the functions locate the terminating
.Ql \e0 .
.Pp
The
.Fn strrchr
function is identical to
.Fn strchr
except it locates the last occurrence of
.Fa c .
.Sh RETURN VALUES
The functions
.Fn strchr
and
.Fn strrchr
return a pointer to the located character, or
.Dv NULL
if the character does not appear in the string.
