5.1.5. DapiOpenModuleEx
Description
This function opens a specific module with ethernet interface. The particularity
of this command is, that parameters like IP-address, portnumber and timeout
can be specified.
Definition
ULONG DapiOpenModuleEx(ULONG moduleID, ULONG nr, unsigned char* exbuffer,
0);
Parameters
moduleID = Specifies the module, which is to be opened (see delib.h)
nr = Indicates No of module which is to be opened.
nr = 0 -> 1. module
nr = 1 -> 2. module
exbuffer = buffer for IP-adresse, port and timeout
Return value
handle = handle to the corresponding module
handle = 0 -> Module was not found
Remarks
The handle returned by this function is needed to identify the module for all
other functions.
This command is only support by modules with ethernet interface.
Example program
// Open ETH-Module with parameter
DAPI_OPENMODULEEX_STRUCT open_buffer;
strcpy((char*) open_buffer.address, "192.168.1.10");
open_buffer.portno = 0;
open_buffer.timeout = 5000;
handle = DapiOpenModuleEx(RO_ETH, 0, (unsigned char*) &open_buffer, 0);
printf("Module handle = %x\n", handle);
