Synopsis

#include <mongoc.h>
#ifdef _WIN32
typedef struct
{
 u_long iov_len;
 char *iov_base;
} mongoc_iovec_t;
#else
typedef struct iovec mongoc_iovec_t;
#endif

The mongoc_iovec_t structure is a portability abstraction for consumers of the mongoc_stream_t interfaces. It allows for scatter/gather I/O through the socket subsystem.

NOTE

When writing portable code, beware of the ordering of iov_len and iov_base as they are different on various platforms. Therefore, you should not use C initializers for initialization.
