NAME

hm2_bspi_set_read_function − Register a function to handle the tram write phase of a hostmot2 buffered SPI driver.

SYNTAX

int hm2_bspi_set_read_function(char *name, void *func, void *subdata)

DESCRIPTION

hm2_bspi_set_read_function Registers a function in an external driver (typically written in "comp") to be called every time that the main Hostmot2 driver calls the generic "process_tram_read" functionsread.
The names of the available channels are printed to standard output during the driver loading process and take the form: hm2_<board name>.<board index>.bspi.<index> For example hm2_5i23.0.bspi.0
"func" should be a pointer to a function in the sub driver which is to be called to process the results of the BSPI TRAM read phase. The function must take a single argument, a pointer to an individual instance of the internal driver. If defined in comp then the function must /fBnot/fP use the FUNCTION() convenience macro, and the argument to the function in the definition must read/fBallways/fP be (struct state *inst).
"subdata" is a pointer to the driver instance internal data. In the case of a driver written in comp this will always be "inst" in the function call and the call should be anywhere in the EXTRA_SETUP code.

RETURN VALUE

Returns 0 on success and -1 on failure.
