Member Function Documentation

alloc()

GAIA_NODISCARD void * gaia::mem::detail::SmallBlockAllocatorImpl::alloc ( uint32_t  bytesWanted )

inline

Allocates storage for up to 512 bytes.

Parameters

bytesWanted

Requested usable bytes.

Returns

Pointer to aligned usable storage.

flush()

void gaia::mem::detail::SmallBlockAllocatorImpl::flush ( bool  releaseAll = false )

inline

Flushes unused pages.

Parameters

releaseAll

When true, all empty pages are released.

free()

void gaia::mem::detail::SmallBlockAllocatorImpl::free ( void *  pBlock )

inline

Releases storage allocated for the given pointer.

Parameters

pBlock

Pointer previously returned by alloc().
