NAME

mongoc_stream_readv() - This function is identical to mongoc_stream_read() except that it takes a mongoc_iovec_t to perform gathered I/O.

SYNOPSIS

ssize_t
mongoc_stream_readv (mongoc_stream_t *stream,
                     mongoc_iovec_t  *iov,
                     size_t           iovcnt,
                     size_t           min_bytes,
                     int32_t          timeout_msec);

PARAMETERS

stream
A mongoc_stream_t \&.

iov
A vector of mongoc_iovec_t \&.

iovcnt
The number of items in iov \&.

min_bytes
The minimum number of bytes to read or failure will be indicated.

timeout_msec
A timeout in milliseconds, or 0 to indicate non-blocking. A negative value with use the default timeout.

This function is identical to mongoc_stream_read(3) except that it takes a mongoc_iovec_t to perform gathered I/O.
