Mat_VarReadInfo — Reads the information for a specific variable in a MATLAB MAT file.

       The Mat_VarReadInfo() function reads the information for the variable name in the open MAT file.

       #include "matio.h"

       int
       main(int argc, char **argv)
       {
           mat_t    *matfp;
           matvar_t *matvar;

           matfp = Mat_Open(argv[1], MAT_ACC_RDONLY);
           if ( NULL == matfp ) {
               fprintf(stderr, "Error opening MAT file %s0, argv[1]);
               return EXIT_FAILURE;
           }

           matvar = Mat_VarReadInfo(matfp, "x");
           if ( NULL != matvar ) {
               Mat_VarPrint(matvar);
               Mat_VarFree(matvar);
           }

           Mat_Close(matfp);
           return EXIT_SUCCESS;
       }

       Mat_VarReadInfo — Reads the information for a specific variable in a MATLAB MAT file.

       If  the  variable  was  found in the MAT file and the information about the variable successfully read, a
       pointer to the MATLAB variable structure is returned.  If the variable was not found,  or  there  was  an
       error reading the variable information, NULL is returned.
