f_initvolume()

[FreeRTOS Embedded File System API]

header_file.h 
unsigned char f_initvolume( F_DRIVERINIT pxInitFunction );
Initialises the embedded FAT file system volume. f_initvolume() must be called before any file system operations can be performed.

f_initvolume() works independently of the status of the hardware, it does not matter if a card is inserted or not.

Parameters:

pxInitFunction   A pointer to the function used to initialise the drive.

Returns:

F_NO_ERROR   The drive was initialised successfully.

Any other value   The drive was not initialised successfully - the return value holds the error code.

See also:

f_format(), f_delvolume().

Example usage: 



void vInitFAT( void )

{

unsigned char ucReturn;



    /* Initialise the drive */

    ucReturn = f_initvolume();

    if( ucReturn != F_NO_ERROR )

    {

        /* Volume was not initialised, ucReturn holds the error code. */

    }

    else

    {

        /* Volume was initialised. */

    }

}
