Detailed Description

Dump memory block.

Definition at line 122 of file dumpmemory.hpp.

Constructor & Destructor Documentation

DumpMemoryBlock::DumpMemoryBlock

(

size_t

size = 0

)

Checks canaries in this dump memory area.

If any canary has been changed, this function aborts the VM with an error message. Allocate a memory block for the current dump memory block.

Parameters

size	Required memory size.

Definition at line 242 of file dumpmemory.cpp.

DumpMemoryBlock::~DumpMemoryBlock

(

)

Release the memory block for the dump memory block.

Parameters

size	Required memory size.

Definition at line 262 of file dumpmemory.cpp.

Member Function Documentation

void * DumpMemoryBlock::allocate ( size_t  size )

inline

Allocate memory in the current dump memory area.

This function is a fast allocator suitable for scratch memory that can be collectively freed when the current activity (eg. compiling) is done.

You cannot selectively free dump memory. Before you start allocating it, you remember the current size returned by dumpmemory_marker. Later, when you no longer need the memory, call dumpmemory_release with the remembered size and all dump memory allocated since the call to dumpmemory_marker will be freed.

size Size of block to allocate in bytes. May be zero, in which case NULL is returned

Returns

Pointer to allocated memory, or NULL iff size was zero.
