iovec - data storage structure for I/O using uio


#include <sys/uio.h> 

Interface Level

Architecture independent level 1 (DDI/DKI).


An iovec structure describes a data storage area for transfer in a uio(9S) structure. Conceptually, it can be thought of as a base address and length specification.

Structure Members

caddr_t    iov_base;  /* base address of the data storage area */
                      /* represented by the iovec structure */ 
int        iov_len;   /* size of the data storage area in bytes */
