SysSockSelect (FUN) ¶ FUNCTION SysSockSelect : DINT This routine permits a task to pend until one of a set of sockets handles becomes ready. Three parameters – fdRead, fdWrite and fdExcept – point to file descriptor sets in which each array entry corresponds to a particular socket handle. If a socket handle is not ready, it will be written in the array to -1 (SOCKET_INVALID). With the timeout value, a timeout for the operation can be specified. diWidth is the size of the fd_array array in SOCKETFD_SET. The function returns the operating system result. <0: Error 0: Timeout expired >0: Typically number of sockets that are successully selected InOut: Scope Name Type Comment Return SysSockSelect DINT Input diWidth DINT Typically SOCKET_FD_SETSIZE fdRead DWORD Address of SOCKET_FD_SET fdWrite DWORD Address of SOCKET_FD_SET fdExcept DWORD Address of SOCKET_FD_SET ptvTimeout DWORD Address of SOCKET_TIMEVAL
