[Creating a FreeRTOS+FAT Media Driver]
FF_IOManager_t *FF_CreateIOManger( FF_CreationParameters_t *pxParameters, FF_Error_t *pxError );
FreeRTOS+FAT media drivers store information that is common to all media types in a structure of type FF_Disk_t. The pxIOManager member of the FF_Disk_t structure references an object called an input/output manager (IO Manager, or simply IOMAN). The IO manager is responsible for, amongst other things, buffering and caching both file and directory information.
FF_CreateIOManager() creates an IO Manager object.
Parameters are passed into FF_CreateIOManager() in an FF_CreationParameters_t structure.
The pvSemaphore member of the FF_CreationParameters_t structure must be created by a call to the xSemaphoreCreateRecursiveMutex() FreeRTOS API function.
A structure of type FF_CreationParameters_t, which
defines the IO manager being created.
Used to pass out an error code.
If the IO manager was created successfully then a pointer to the created IO manager is returned and *pxError is set to FF_ERR_NONE. If the IO manager was not created successfully then NULL is returned and *pxError is set to an error code. FF_GetErrMessage() converts error codes into error descriptions.
The page that documents how to create a FreeRTOS+FAT media driver also demonstrates how to use the FF_CreateIOManger() function.
