SETIOV()

Fill in the fields of an iov_t structure

Synopsis:

#include <sys/types.h>
#include <unistd.h>

void SETIOV( iov_t *msg,
             void *addr,
             size_t len );

The SETIOV() macro fills in the fields of an iov_t message structure. The iov_t structure consists of two fields:

typedef struct iovec {
    void    *iov_base;
    size_t   iov_len;
} iov_t;

Note: SETIOV() doesn't make a copy of the data that addr points to; it just copies the pointer.
