Function Documentation

cpr_memalloc()

void * cpr_memalloc

(

size_t

size

)

Portable memory allocation helper function.

Handles out of heap error as a runtime error.

Parameters

size	of memory block to allocate from heap.

Returns

memory address of allocated heap space.

cpr_memassign()

void * cpr_memassign	(	size_t	size,
		caddr_t	address,
		size_t	known )

Portable memory placement helper function.

This is used to process "placement" new operators where a new object is constructed over a pre-allocated area of memory. This handles invalid values through runtime error.

Parameters

size	of object being constructed.
address	where the object is being placed.
known	size of the location we are constructing the object in.

cpr_memswap()

void cpr_memswap	(	void *	mem1,
		void *	mem2,
		size_t	size )

Portable swap code.

Parameters

mem1	to swap.
mem2	to swap.
size	of swap area.

cpr_runtime_error()

void cpr_runtime_error

(

const char *

text

)

Function to handle runtime errors.

When using the standard C library, runtime errors are handled by a simple abort. When using the stdc++ library with stdexcept, then std::runtime_error will be thrown.

Parameters

text	of runtime error.

freep()

template<typename T >

void freep

(

T **

handle

)

newp()

template<typename T >

T * newp

(

T **

handle

)

Definition at line 176 of file cpr.h.
