Function Documentation

void* cpr_memalloc ( size_t  size)

Portable memory allocation helper function.

Handles out of heap error as a runtime error.

Parameters:
sizeof memory block to allocate from heap.
Returns:
memory address of allocated heap space.
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:
sizeof object being constructed.
addresswhere the object is being placed.
knownsize of the location we are constructing the object in.
void cpr_memswap ( void *  mem1,
void *  mem2,
size_t  size 
)

Portable swap code.

Parameters:
mem1to swap.
mem2to swap.
sizeof swap area.
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:
textof runtime error.
