missing prototype

[raj129*]

hi,

i am trying to call the function defined in dll written in VC++. i am getting missing prototype error even though if i include respective header files. when i was calling a function with one or many arguments in it it is working fine. i am getting missing protype error when i was trying to call a function without any argument. this might be silly but i could not identify where the problem is ? please help me.

Hi,

help is (much) easier if you provide the relevant code snippet...

i am facing missing prototype error when i am trying to call the below 2 function 

long _stdcall MSDEcmIO_CloseCommunication();

long _stdcall MSDEcmIO_OpenCommunication();

but it is working fine with the below funs

long _stdcall MSDEcmIO_ReadECMChannelData(unsigned short usMID,long lChannelType,char * pstrLocation,long lDataSize,long lDisplayType,long lStorageType, double dSlope,double dOffset,char* pData, long * plSizepData, long lTimeout);

ok: if a function has no argument, you need to use void as its argument:

function ( void )
