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.
BUGS
