Member Function Documentation

allocate()

size_t STK::BuddyAllocator::allocate ( size_t  sizeBytes )

inline

Allocate bytes. This method will allocate sizeBytes and return a byte offset (aligned to block size) to the start of the allocated memory. Will return npos on error. This method grows automatically (by doubling) until it succeeds.
