memcmp
Compares the first n characters of two objects.
Syntax
#include <string.h>
int memcmp(const void *s1, const void *s2, size_t n);
Parameters
s1 A pointer to the first object.
s2 A pointer to the second object.
n The number of characters to compare.
Return Values
<0 s1 is less than s2.
0 s1 is equal to s2.
>0 s1 is greater than s2.
Description
The memcmp function compares the first n characters of the object pointed
to by s1 to the first n bytes of the object pointed to by s2. The result
is returned as an integer. Null characters in the objects do not cause
this comparison function to stop.
The contents of "holes" used as padding for alignment with structure
objects are indeterminate. Strings shorter than their allocated space
and unions can also cause comparison problems.
