+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.
