FUNCTION SysSockRecv : __XINT

Receive data from a TCP socket.

InOut:

Scope	Name	Type	Comment
Return	`SysSockRecv`	`__XINT`	Number of bytes received. 0 if failed.
Input	`hSocket`	`RTS_IEC_HANDLE`	Handle to the socket
	`pbyBuffer`	POINTER TO BYTE	Buffer to read data from the socket
	`diBufferSize`	`__XINT`	Maximum length of the buffer
	`diFlags`	`DINT`	The flags parameter can be used to influence the behavior of the function beyond the options specified for the associated socket. The semantics of this function are determined by the socket options and the flags parameter. The latter is constructed by using the bitwise OR operator with any of the SOCKET_MSG values.
