Platform-specific public function prototype declaration specification.
Some platforms make use of this identifier to specially mark public functions (e.g., for library import/export, etc.). By default, this inherits from the platform default given by DOF_PCR_DECLSPEC (if defined by the PCR), or is empty. Specifies an infinite timeout. DOF_TIMEOUT_NEVER can be used in any call that accepts a timeout to indicate that the operation will never time out. Of course, the operation may still be canceled or terminate for other reasons.
