NAME

index − string operation

SYNOPSIS

int index (s1, s2)
char ∗s1, ∗s2;

DESCRIPTION

The arguments s1 and s2 point to strings (arrays of characters terminated by a null character). 

index returns the offset of the first occurrence of string s2 in string s1, or a -1 if s2 does not occur in the string.

NOTE

This version of index is different from the version in /lib/libc.a.
