f_seteof()

[FreeRTOS Embedded File System API]

header_file.h 
int f_seteof( F_FILE *pxFileHandle );

Truncates a file to the current file read/write position. All data after the current read/write position is lost.

Parameters:

pxFileHandle   The handle of the file being truncated. The handle is returned by the call to f_open() originally used to open the file.

Returns:
F_NO_ERROR   The file was successfully truncated.

Any other value   The file was not successfully truncated. The returned value holds the error code.

Example usage: 



void vSampleFunction( char *pcFileName, long lTruncatePosition )

{

F_FILE *pxFile;



    /* Open the file specified by the pcFileName parameter. */

    pxFile = f_open( pcFileName, "r+" );



    /* Move the current read/write position to the position specified by

    the lTruncatePosition parameter. */

    f_seek( pxFile, lTruncatePosition, F_SEEK_SET );



    /* Truncate the file so all data past the current file position is lost. */

    if( f_seteof( pxFile ) != F_NO_ERROR )

    {

        /* The truncate failed. */

    }



    /* Finished with the file. */

    f_close( pxFile );

}
