SYNOPSIS

s1 string

DESCRIPTION
|
|
Let n1 = size(s1), n2 = size(n2), and m = min(n1, n2, n).
|
|
This function replaces the first m characters of s1 by the first
|
|
m characters of s2, and if min(n1, n) > n2, replaces the next
|
|
min(n1,n) - n2 characters of s1 by '\0'. The size of s1 and any
|
|
later characters of s1 are unchanged. The function returns s1, with
|
|
new value.
