Macro Definition Documentation

CMRallocStack

#define CMRallocStack	(		cmr,
			ptr
	)		_CMRallocStack(cmr, (void**) ptr, sizeof(**ptr))

Allocates statck memory for *ptr.

Stack memory shall be freed with CMRfreeStack in the reverse order of allocation. The size is determined automatically.

CMRallocStackArray

#define CMRallocStackArray	(		cmr,
			ptr,
			length
	)		_CMRallocStack(cmr, (void**) ptr, sizeof(**ptr) * (length))

Allocates memory for an array of blocks on the stack.

CMRdbgConsistencyAssert

#define CMRdbgConsistencyAssert

(

call

)

CMRfreeStack

#define CMRfreeStack	(		cmr,
			ptr
	)		_CMRfreeStack(cmr, (void**) ptr, sizeof(**ptr))

Frees a stack memory chunk allocated with CMRallocStack.

CMRfreeStackArray

#define CMRfreeStackArray	(		cmr,
			ptr
	)		_CMRfreeStack(cmr, (void**) ptr)

Frees memory of an array of blocks on the stack.

Function Documentation

_CMRallocStack()

CMR_EXPORT CMR_ERROR _CMRallocStack	(	CMR *	cmr,
		void **	ptr,
		size_t	size
	)

Carries out the allocation for CMRallocStack.

Note

Use CMRallocStack to allocate stack memory.

Parameters

cmr	CMR environment.
ptr	Pointer where the space shall be allocated.
size	Space to allocate.

_CMRfreeStack()

CMR_EXPORT CMR_ERROR _CMRfreeStack	(	CMR *	cmr,
		void **	ptr
	)

Carries out the deallocation for CMRfreeStack.

Note

Use CMRfreeStack to free stack memory.

Parameters

cmr	CMR environment.
ptr	Pointer of space to be freed.

CMRassertStackConsistency()

void CMRassertStackConsistency

(

CMR *

cmr

)

Checks stack protection fields for corruption.

Useful for debugging memory errors.

Parameters

			...
	)

CMRdbgMsg()

static void CMRdbgMsg ( int  indent, const char *  format,   ...  )

CMRgetStackUsage()

size_t CMRgetStackUsage

(

CMR *

cmr

)

Parameters

CMRraiseErrorMessage()

void CMRraiseErrorMessage	(	CMR *	cmr,
		const char *	format,
			...
	)

Parameters

cmr	CMR environment.
format	Format string in printf-style.
...	Variadic arguments.
