Member Function Documentation

void cxx::List_alloc::free ( void *  block, unsigned long  size, bool  initial_free = false  )

inline

Return a free memory block to the allocator.

Parameters

block	pointer to memory block
size	size of memory block
initial_free	Set to true for putting fresh memory to the allocator. This will enforce alignment on that memory.

void * cxx::List_alloc::alloc ( unsigned long  size, unsigned  align  )

inline

Alloc a memory block.

Parameters

size	Size of the memory block
align	Alignment constraint

Returns

Pointer to memory block

Definition at line 238 of file list_alloc.

unsigned long cxx::List_alloc::avail ( )

inline

Get the amount of available memory.

Returns

Available memory in bytes
