F_READSECTOR()

[FreeRTOS File System Media Driver API]

header_file.h

typedef int ( *F_READSECTOR )( F_DRIVER * pxDriver, void * pvBuffer, unsigned long ulSector );

The implementation must read a single sector from the physical media.

Parameters:

pxDriver	A pointer to the F_DRIVER structure returned by the call to F_DRIVERINIT() originally used to initialise the drive from which the sector is to be read.
pvBuffer	A pointer to the buffer into which the data read from the sector is to be written.
ulSector	The number of the sector to be read.

Returns:

0	The sector was read from the physical media.
Any other value	The sector number was out of range.

Example usage:

A worked example is provided in the RAM disk driver available from this web site.
