The send() call sends the number of bytes specified by the ''len'' parameter, from the memory pointed to by ''buf'' to the socket specified by ''sockfd''. The flags parameter is currently not used. <br /> <br /> The assembly language interface sends the contents of memory pointed to by the DE register pair, with the number of bytes to send specified in the BC register pair. The accumulator contains the socket number.<br /> <br /> == Return values ==<br /> <br /> On successful return, the C function returns the number of bytes sent. On error, the C function returns -1.<br /> <br /> The assembler interface returns the number of bytes sent in the BC register pair. On error, the carry flag is set and the A register contains the error code.<br /> <br /> [[Category:Spectranet]]</div>
