NAME

       vrb_move - read data into a VRB

LIBRARY

       -lvrb

SYNOPSIS

       #include <vrb.h>

       size_t vrb_move(vrb_p target, vrb_p source, size_t size);

DESCRIPTION

       vrb_move  moves	data from one virtual ring buffer to another, up to the lesser of the available data in the source, the available space in
       the target, and the maximum size specified.

ARGUMENTS

       vrb_p target
       specifies which virtual ring buffer to put data into.

       vrb_p source
       specifies which virtual ring buffer to get data from.

       size_t size
       specifies the maximum length to move, or ~0 for unlimited (all of buffer).

RETURN VALUE

       size_t
       If successful, the actual length of data moved is returned.  If an error occurs, ~0 is returned.

ERRORS

       If an error is returned, then errno will have the following value:

       EINVAL An invalid virtual ring buffer pointer was specified for either the target or the source.
