Typedef Documentation

TFFS_Error_Handler

The prototype for the TFFS EEPROM error handler callback. This callback may be installed by using tffsIoctl() with function code TFFS_IOC_ERROR_HANDLER. Parameters: error  The error code reported by the EEPROM driver. drv  The TFFS drive number which reported the error. offset  The offset into the EEPROM bank at which the error occurred. userArg  The user argument passed to tffsIoctl().

TFFS_IOC

The typedef for _TFFS_IOC.

Function Documentation

STATUS tffsIoctl (  TFFS_IOC  funcCode, int  arg0, int  arg1, int  arg2 )

TFFS driver low-level control. This function provides extended control over the EEPROM MTD driver not available with the standard VxWorks TFFS interface. The funcCode parameter specifies the action to perform. TFFS_IOC_ERROR_HANDLER - Installs a callback which will catch EEPROM MTD driver errors. Set arg0 to the address of the function and arg1 to a user parmeter value which will be passed to the callback. The callback is in the form TFFS_Error_Handler. Parameters: funcCode  One of the TFFS_IOC values specifying the action to take. arg0  Function specific parameter. arg1  Function specific parameter. arg2  Function specific parameter. Return values: OK  Success. ERROR  Error.
