gnutls_record_send_file - API function
#include <gnutls/gnutls.h>
ssize_t gnutls_record_send_file(gnutls_session_t session, int fd,
off_t * offset, size_t count);
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.
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.
The number of bytes sent, or a negative error code.
