mlfFerror (MATLAB C Math Library)

Query MATLAB about errors in file input or output

C Prototype

mxArray *mlfFerror(mxArray **errnum, mxArray *fid,
                    mxArray *clear);

C Syntax

#include "matlab.h"

mxArray *fid;          /* Required input argument(s) */
mxArray *clear;        /* Optional input argument(s) */
mxArray *errnum = NULL;/* Optional output argument(s) */
mxArray *message = NULL;/* Return value */

mlfAssign(&message, mlfFerror(NULL,fid,NULL));
mlfAssign(&message, mlfFerror(NULL,fid,

mxCreateString("clear"));

mlfAssign(&message, mlfFerror(&errnum,fid,NULL));
mlfAssign(&message, mlfFerror(&errnum,fid,

mxCreateString("clear"));

MATLAB Syntax

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