set_bus_speed function
QNX SDP8.0Customizing a BSPConfigurationDeveloper
The set_bus_speed function specifies the bus speed. If an invalid bus speed is requested, this function should return a failure and leave the bus speed unchanged. The prototype for this function is:
int set_bus_speed(
void *hdl,
unsigned int speed,
unsigned int *ospeed );
The arguments are:
- hdl
- The handle returned by the init function.
- speed
- The bus speed. The units are implementation-defined.
- ospeed
- NULL, or a pointer to a location where the function should store the actual bus speed.
The function must return:
- 0
- Success.
- -1
- Failure.
