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.
