uio.h, uio - definitions for vector I/O operations
#include <sys/uio.h>
The <sys/uio.h> header defines the iovec structure, which includes the following members:
void *iov_base /* base address of a memory region
for input or output */
size_t iov_len /* size of the memory pointed to by
iov_base */
The <sys/uio.h> header uses the iovec structure for scatter/gather I/O.
The ssize_t and size_t types are defined as described in <sys/types.h>.
The symbol {IOV_MAX} defined in <limits.h> should always be used to learn about the limits on the number of scatter/gather elements that can be processed in one call, instead of assuming a fixed value.
See attributes(5) for descriptions of the following attributes:
