NAME
|
|
strcmp - compare two strings in the customary ordering of strings
|
|
|
|
SYNOPSIS
|
|
strcmp(s1, s2)
|
|
|
|
TYPES
|
|
s1 string
|
|
s2 string
|
|
|
|
return integer (1, 0 or -1)
|
|
|
|
DESCRIPTION
|
|
Let n1 = size(s1), n2 = size(s2) and m = min(n1, n2).
|
|
This function compares up to m values of consecutive characters
|
|
in the strings s1 and s2. If an inequality is encountered, the
|
|
function returns 1 or -1 according as the greater character is
|
|
in s1 or s2. If there has been no inequality, the function
|
|
returns 1, 0, or -1 according as n1 is greater than, equal to,
|
|
or less than n2.
|
|
Note that null characters within the strings are included in the
|
|
comparison.
