MONGOC_IOVEC_T(3) Library Functions Manual MONGOC_IOVEC_T(3)

NAME

mongoc_iovec_t - 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

SYNOPSIS

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.
