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. */
}
}
