Function Documentation
| RTEMS_INLINE_ROUTINE bool _ASR_Are_signals_pending | ( | ASR_Information * | information | ) |
ASR_Are_signals_pending.
This function returns TRUE if there are signals pending in the given RTEMS_ASR information record and FALSE otherwise.
References ASR_Information::signals_posted.
| RTEMS_INLINE_ROUTINE void _ASR_Initialize | ( | ASR_Information * | information | ) |
ASR_Initialize.
This routine initializes the given RTEMS_ASR information record.
References ASR_Information::is_enabled, ASR_Information::handler, ASR_Information::mode_set, RTEMS_DEFAULT_MODES, ASR_Information::signals_posted, ASR_Information::signals_pending, and ASR_Information::nest_level.
| RTEMS_INLINE_ROUTINE bool _ASR_Is_null_handler | ( | rtems_asr_entry | asr_handler | ) |
ASR_Is_null_handler.
This function returns TRUE if the given asr_handler is NULL and FALSE otherwise.
| RTEMS_INLINE_ROUTINE void _ASR_Post_signals | ( | rtems_signal_set | signals, |
| rtems_signal_set * | signal_set | ||
| ) |
ASR_Post_signals.
This routine posts the given signals into the signal_set passed in. The result is returned to the user in signal_set.
NOTE: This must be implemented as a macro.
References _ISR_Disable, and _ISR_Enable.
| RTEMS_INLINE_ROUTINE void _ASR_Swap_signals | ( | ASR_Information * | information | ) |
ASR_Swap_signals.
This routine atomically swaps the pending and posted signal sets. This is done when the thread alters its mode in such a way that the RTEMS_ASR disable/enable flag changes.
References _ISR_Disable, ASR_Information::signals_pending, ASR_Information::signals_posted, and _ISR_Enable.
