gnutls_record_send_file(3) gnutls gnutls_record_send_file(3) NAME gnutls_record_send_file - API function SYNOPSIS #include <gnutls/gnutls.h> ssize_t gnutls_record_send_file(gnutls_session_t 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 follow- ing last read byte. size_t countis 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 be- tween 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_trans- port_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.
