* The success of this routine can be determined via the \ ref Endpoint_IsConfigured ( ) macro .
*
* By default , the routine is entirely dynamic , and will accept both constant and variable inputs .
* If dynamic configuration is unused , a small space savings can be made by defining the
* STATIC_ENDPOINT_CONFIGURATION macro via the - D switch to the compiler , to optimize for constant
* input values .
*
* \ note This routine will select the specified endpoint , and the endpoint will remain selected
* once the routine completes regardless of if the endpoint configuration succeeds .
