MATLAB: How to pass char** parameter to C function using calllib

Question

Hello,

I would like to know how to pass a char** argument to a C function ('test1DChar'). The signature of test1DChar is the following:

void test1DChar (char **data, int *size);

Here is my test code for calling the C function:

sizePtr = libpointer('int32Ptr', 0);
data = ????
calllib ('libfun','test1DChar', data, sizePtr);

Thank you for your help.

Regards,

LF

I've finally found a solution:

data = libpointer('stringPtrPtr', cell(1, 1));

Hope it can help. LF
