ff_rewind()

[FreeRTOS-Plus-FAT Standard API Reference]

ff_stdio.h 
void ff_rewind( FF_FILE *pxStream );

Moves the current read/write position back to the start of a file.

Calling...
ff_rewind( pxStream );

...is equivalent to calling
( void ) ff_fseek( pxStream, 0, FF_SEEK_SET );.

Parameters:

pxStream   The file in which the current read/write position is being set back to the start of the file.

Example usage: 



void vSampleFunction( void )

{

char pcBuffer1[ 4 ], pcBuffer2[ 4 ];

FF_FILE *pxFile;



    /* Open the file "afile.bin". */

    pxFile = ff_fopen( "afile.bin", "r" );



    if( pxFile != NULL )

    {

        /* Read four bytes into pcBuffer1. */

        ff_fread( pcBuffer1, 4, 1, pxFile );



        /* Set the current read pointer back to the start of the file. */

        ff_rewind( pxFile );



        /* Read the same four bytes into pcBuffer2. */

        ff_fread( pcBuffer2, 4, 1, pxFile );



        /* Finished with the file. */

        ff_fclose( pxFile );

    }

}
