MAT_VARREADNEXT(3)	 BSD Library Functions Manual	    MAT_VARREADNEXT(3)

NAME
     Mat_VarReadNext --	Reads the information and data for the next variable
     in	a MATLAB MAT file.

SYNOPSIS
     #include <matio.h>

     matvar_t *
     Mat_VarReadNext(mat_t *mat);

DESCRIPTION
     The Mat_VarReadNext() function reads the information and data for the
     next variable stored in the open MAT file.

RETURN VALUES
     If	there is another variable in the MAT file and is read successfully, a
     pointer to	the MATLAB variable structure is returned. If there are	no
     more variables, or	there was an error reading the variable, NULL is re-
     turned.

EXAMPLES
     This example program opens	a MAT file named by the	first argument to the
     program, and uses Mat_VarReadNext() to read each variable in the file.
     For each variable read, the Mat_VarPrint(3) function is used to display
     the information and data of the variable.

     #include <stdlib.h>
     #include <stdio.h>
     #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;
	 }

	 while ( NULL != (matvar = Mat_VarReadNext(matfp)) ) {
	     Mat_VarPrint(matvar,1);
	     Mat_VarFree(matvar);
	 }

	 Mat_Close(matfp);
	 return	EXIT_SUCCESS;
     }
