Mat_VarReadInfo(3)       BSD Library Functions Manual       Mat_VarReadInfo(3)


NAME

     Mat_VarReadInfo -- Read the information for a specific variable in a MAT-
     LAB MAT file.


SYNOPSIS

     #include <matio.h>

     matvar_t *
     Mat_VarReadInfo(mat_t *mat, const char *name);


DESCRIPTION

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


RETURN VALUES

     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.


EXAMPLES

     #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;
     }
