NAME
iovec - Vector I/O data structure
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)).
STANDARDS
POSIX.1-2008.
HISTORY
POSIX.1-2001.
NOTES
The following header also provides this type: <sys/socket.h>.
