+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.
