Is there a way to calculate “cksum” from C code.
Or to capture the output from a spawned cksum?

popen()

ccitt checksum source code are avaible on the web.
If you can’t find it I could dig it out and post it.

Thanks Mario-I have source like this.
I was hoping there was this qnx_cksum() function
that takes a filename and spits out the cksum, same as the
cksum utilitity, but looks I’m out of luck.

The POSIX checksum algorithm should be coded in GNU, Linux, FreeBSD,
etc.
