NAME
gnutls_record_send_file - API function
SYNOPSIS
#include <gnutls/gnutls.h>
gnutls_record_send_file(3) session, int fd, off_t *
offset, size_t count);
ARGUMENTS
gnutls_session_t session
is a gnutls_session_t type.
int fd file descriptor from which to read data.
off_t * offset
Is relative to file offset, denotes the starting location for
reading. after function returns, it point to position
following last read byte.
size_t count
is the length of the data in bytes to be read from file and
send.
DESCRIPTION
This function sends data from fd . If KTLS (kernel TLS) is enabled, it
will use the sendfile() system call to avoid overhead of copying data
between user space and the kernel. Otherwise, this functionality is
merely emulated by calling read() and gnutls_record_send(). If this
implementation is suboptimal, check whether KTLS is enabled using
gnutls_transport_is_ktls_enabled().
If offset is NULL then file offset is incremented by number of bytes
send, otherwise file offset remains unchanged.
RETURNS
The number of bytes sent, or a negative error code.
