NAME
|
|
|
|
bcmp -- compare two memory regions
|
|
|
|
SYNOPSIS
|
|
|
|
int bcmp (char *from, char *to, int count)
|
|
|
|
DESCRIPTION
|
|
|
|
Compare two memory regions and return zero if they are identical,
|
|
non-zero otherwise. If count is zero, return zero.
|
|
|
|
NOTES
|
|
|
|
No guarantee is made about the non-zero returned value. In
|
|
particular, the results may be signficantly different than
|
|
strcmp(), where the return value is guaranteed to be less than,
|
|
equal to, or greater than zero, according to lexicographical
|
|
sorting of the compared regions.
