LIBRARY

Standard C library (libc)

SYNOPSIS

#include <sys/uio.h>
struct iovec {
 void *iov_base; /* Starting address */
 size_t iov_len; /* Size of the memory pointed to by 
iov_base. */
};

DESCRIPTION

Describes a region of memory, beginning at iov_base address and with the size of iov_len bytes. System calls use arrays of this structure, where each element of the array represents a memory region, and the whole array represents a vector of memory regions. The maximum number of iovec structures in that array is limited by IOV_MAX (defined in <limits.h>, or accessible via the call sysconf(_SC_IOV_MAX)).
