strchr
, strrchr
— locate character in string
Standard C Library (libc, -lc)
#include
<string.h>
char *
strchr
(const char *s,
int c);
char *
strrchr
(const char *s,
int c);
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 to be
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 functions strchr
() and
strrchr
() return a pointer to the located character,
or NULL
if the character does not appear in the
string.

() and
