STRSTR(3)						     Linux Programmer's Manual							 STRSTR(3)

NAME
strstr, strcasestr - locate a substring SYNOPSIS
#include <string.h> char *strstr(const char *haystack, const char *needle); #define _GNU_SOURCE /* See feature_test_macros(7) */ #include <string.h> char *strcasestr(const char *haystack, const char *needle); DESCRIPTION
The strstr() function finds the first occurrence of the substring needle in the string haystack. The terminating null bytes ('') are not compared. The strcasestr() function is like strstr(), but ignores the case of both arguments. RETURN VALUE
These functions return a pointer to the beginning of the substring, or NULL if the substring is not found. CONFORMING TO
The strstr() function conforms to C89 and C99. The strcasestr() function is a nonstandard extension. BUGS
Early versions of Linux libc (like 4.5.26) would not allow an empty needle argument for strstr(). Later versions (like 4.6.27) work cor- rectly, and return haystack when needle is empty. SEE ALSO
