Use The purpose of this call is to write data to a socket. It is equivalent to calling [[Socket_Send|send()]] with flags of 0. h4. Berkeley sockets equivalence This SWI directly corresponds to the function "write":https://pubs.opengroup.org/onlinepubs/9699919799/functions/write.html and would ordinarily be called from C using the <code>socketwrite()</code> function in <code>socklib.h</code>. h4. Notes The different function name is needed because in RISC OS file descriptors and socket descriptors come from two different number spaces, while under Unix they share the same number space so a single <code>write()</code> function serves to write to either type. h4.
