How to convert to C a function with variable fields in the input?

Hello everybody,
I wish to convert to C a function that have two inputs, a scalar and a file or a struct
[outputs] = myfunction(id, 'myfile.mat') ;
or
[outputs] = myfunction(id, mystruct) ;
myfile.mat or mystruct contain fields which can have different names according to the user's inputs, which are checked by the the function according to the isfield command.
However it looks I cannot define an input type 'file' in the Matlab coder... nor I can leave a struct input without defining all the field names...
Any suggestions, please?
Thanks
Patrizio

You can send a variable that contains full path to the file as an input argument and within the function use load command.
Edit: though I haven't used MATLAB Coder before, so I am not sure whether this will work.

C and C++ do not have dynamic field names. You cannot create a struct or a union with dynamic field names in C -- you could only create a datatype in which there was a list of field names and a list of corresponding pointers to data.
I do not have experience with generated MATLAB code so I do not know if MATLAB Coder provides the interface to the structure maintenance API that you would call from mex routines.
