Query MATLAB about errors in file input or output

C++ Prototype

mwArray ferror(const mwArray &fid);
mwArray ferror(const mwArray &fid, const mwArray &clear);
mwArray ferror(mwArray *errnum, const mwArray &fid);
mwArray ferror(mwArray *errnum, const mwArray &fid,
                const mwArray &clear);

C++ Syntax

#include "matlab.hpp"

mwArray fid;                // Input argument(s)
mwArray errnum;             // Output argument(s) 
mwArray message;            // Return value

message = ferror(fid);
message = ferror(fid,"clear");
message = ferror(&errnum,fid);
message = ferror(&errnum,fid,"clear");

MATLAB Syntax

message = ferror(fid)
message = ferror(fid,'clear')
[message,errnum] = ferror(...)
