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”).
