Return to rmd160.h CVS log

Up to [local] / src / include

Use a common source file for all the hash helper functions that
previously lived in foohl.c.  The foohl.c files are now generated
via sed, though perhaps cpp could be used in the future.

Use u_int8_t instead of unsigned char for the buffers struct fooContext.
Add constants for buffer lengths and use them in function prototypes
and the man pages.

This is basically cosmetic surgery; there should be no functional changes.
