Hi, I'm trying to use the functions ippsSplitC_8u_D2L or ippsSplitC_16u_D2L either with managed C++ or C#, but I'm not able to made them work, I've got problems with parameters.
Does anybody have an example of how they work?
Thank you very much in advance

Hi

did you took a look on IPP C# sample, which demonstartes how to implement C# interface to IPP functions? It also contains interfaces to ippCH functions (string and text processing which you use)

Yes, I did,but I've found just the DllImport declaration of the functions that use unsafe C# code with difficult to manage byte**.
Is there any sample code that show the right way to use them?
Could you post some?
Thank you

Hi,

yes, our expert prepared such a simple sample specially for you:)

#include
#include
#include

int main() {
const Ipp8u States[] = "Alabama Alaska Arizona Arkansas California Colorado Connecticut";
Ipp8u buff[40];
Ipp8u* nameState[4] = { buff, buff + 10, buff + 20, buff + 30 };
int lenNameState[4]= { 10, 10, 10, 10 };
int i, numState = 4;
IppStatus status;

status = ippsSplitC_8u_D2L( (Ipp8u*)States, sizeof(States) - 1, ' ', nameState, lenNameState, &numState );
if( status < ippStsNoErr ) {
printf( "Error "%s" appear in ippsSplitC_8u_D2L function. ", ippGetStatusString( status ) );
return 1;
} /* if */
for( i = 0; i < numState; i++ ) {
*(nameState + lenNameState) = '�';
printf( "State %d: %s; ", i, (char*)(nameState) );
} /* for */
return 0;
} /* main */



This example should ouput on the screen:

State 0: Alabama;
State 1: Alaska;
State 2: Arizona;
State 3: Arkansas;

Vladimir

Im sorry, I could have sworn he was looking for managed code without pointers. I don't see any managed code here. No namespace, and managed C# has no use for headers. Great program, but maybe not quite what he was hoping for...

Thanks,
Ryan
