GetStack()

virtual Word * stk::IStackMemory::GetStack ( ) const

pure virtual

Get pointer to the stack memory.

Here is the caller graph for this function:

GetStackSize()

virtual size_t stk::IStackMemory::GetStackSize ( ) const

pure virtual

Get number of elements of the stack memory array.

Implemented in stk::StackMemoryWrapper< _StackSize >, stk::StackMemoryWrapper< STACK_SIZE_MIN >, stk::StackMemoryWrapper<(32U)>, stk::Task< _StackSize, _AccessMode >, stk::TaskW< _Weight, _StackSize, _AccessMode >, stk::time::TimerHost::TimerWorkerTask, StkThread, and TaskWrapper.

Referenced by GetStackSpace().

Here is the caller graph for this function:

GetStackSizeBytes()

virtual size_t stk::IStackMemory::GetStackSizeBytes ( ) const

pure virtual

Get size of the memory in bytes.

Implemented in stk::StackMemoryWrapper< _StackSize >, stk::StackMemoryWrapper< STACK_SIZE_MIN >, stk::StackMemoryWrapper<(32U)>, stk::Task< _StackSize, _AccessMode >, stk::TaskW< _Weight, _StackSize, _AccessMode >, stk::time::TimerHost::TimerWorkerTask, StkThread, and TaskWrapper.

GetStackSpace()

virtual size_t stk::IStackMemory::GetStackSpace ( )

inlinevirtual

Get available stack space.

Returns

Number of elements of the stack memory array remaining on the stack (computed via the watermark pattern). Returns 0 if the stack has been fully used or the watermark STK_STACK_MEMORY_FILLER was overwritten.

Warning

Stack type: Bottom to Top (index[0]).
