	Number of iovec entries remaining, starting at iov.
std::size_t	iov_offset {0}

Member Data Documentation

iov

const struct iovec* utils::IovIter::iov {}

Points to the first entry that has not been transferred completely. May point past the end of the array when iov_size == 0, so it must not be dereferenced without checking iov_size first.

Definition at line 45 of file iovec_advance.hpp.

iov_offset

std::size_t utils::IovIter::iov_offset {0}

Byte offset within *iov, i.e. the number of bytes of the current entry that were already transferred. 0 means the current entry has not been partially consumed and the list can be reused as is.

Definition at line 53 of file iovec_advance.hpp.

iov_size

std::size_t utils::IovIter::iov_size {}

Number of iovec entries remaining, starting at iov.

Definition at line 48 of file iovec_advance.hpp.
