!!NAME


strstr - locate a substring
!!SYNOPSIS


__#include
__''haystack''__, const char *__''needle''__);
__
!!DESCRIPTION


The __strstr()__ function finds the first occurrence of
the substring ''needle'' in the string ''haystack''.
The terminating `0' 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.
