Description

vrb_give specifies how much data has been placed into the empty portion of the virtual ring buffer by the caller.

The caller will have called vrb_empty_len(3) and vrb_empty_ptr(3) to get the length of empty space in the buffer and a pointer to it, and having placed some data into that space, starting from the pointer obtained and placing no more that the length obtained.

Arguments

specifies which virtual ring buffer.

size_t size
specifies the length of data that has been placed into the virtual ring buffer empty space by the caller.

Return Value

int
On success, 0 is returned. On error, -1 is returned.

If an error is returned, then errno will have one of the following values:
EINVAL
An invalid virtual ring buffer pointer was specified.
ENOSPC
The specified length is greater than the empty space in the virtual ring buffer.
