6.1.5. DapiOpenModuleEx
Description
This function opens a specific RO-ETH-module.The particularity of this
command is, that parameters like IP-address and portnumber can be specified.
Definition
ULONG DapiOpenModuleEx(ULONG moduleID, ULONG nr, unsigned char*
exbuffer);
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 and port
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.
Currently, this command is only supported by our RO-ETH-Series.
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;
handle = DapiOpenModuleEx(RO_ETH, 0, (unsigned char*) &open_buffer);
printf("Module handle = %x\n", handle);
