NAME
strchr, strrchr
— locate character in
string
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include
<string.h>
char *
strchr(const char *s,
int c);
char *
strrchr(const char *s,
int c);
DESCRIPTION
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.
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.

STANDARDS
The functions strchr() and
strrchr() conform to ISO/IEC
9899:1990 (“ISO C90”).
