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 );
Arguments:
- msg
- A pointer to the iov_t structure structure that you want to set.
- addr
- The value you want to use for the structure's iov_base member.
- len
- The value you want to use for the structure's iov_len member.
Description:
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;
SETIOV() doesn't make a copy of the data that addr
points to; it just copies the pointer.
