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 may 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 */
