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

NAME
strstr - locate a substring SYNOPSIS
#include <string.h> char *strstr(const char *haystack, const char *needle); DESCRIPTION
The strstr() function finds the first occurrence of the substring needle in the string haystack. The terminating `' characters are not compared. RETURN VALUE
The strstr() function returns a pointer to the beginning of the substring, or NULL if the substring is not found. BUGS
Early versions of Linux libc (like 4.5.26) would not allow an empty argument. Later versions (like 4.6.27) work correctly, and return haystack when needle is empty. CONFORMING TO
