Detailed Description

This group contains the Classic API task modes.

Macro Definition Documentation

◆ RTEMS_INTERRUPT_LEVEL

#define RTEMS_INTERRUPT_LEVEL ( _interrupt_level ) ( ( _interrupt_level ) & RTEMS_INTERRUPT_MASK )

Maps the interrupt level to the associated processor-dependent task mode interrupt level.

Parameters

_interrupt_level is the interrupt level to map.

Returns: Returns the processor-dependent task mode interrupt level associated with the interrupt level.

Notes: The Classic API supports 256 interrupt levels using the least significant eight bits of the mode set. On any particular processor variant, fewer than 256 levels may be supported. At least level 0 (all interrupts enabled) and level 1 (interrupts disabled, on most architectures) are supported.

Function Documentation

◆ rtems_interrupt_level_body()

rtems_mode rtems_interrupt_level_body ( uint32_t level )

Maps the interrupt level to the associated processor-dependent task mode interrupt level.

Parameters

level is the interrupt level to map.

Returns: Returns RTEMS_INTERRUPT_LEVEL() for the interrupt level.

Notes: This function is used by bindings from languages other than C and C++.

Variable Documentation

◆ rtems_interrupt_mask

const uint32_t rtems_interrupt_mask

extern

This task mode constant has the same value as RTEMS_INTERRUPT_MASK.
