Void specialization of the standard allocation policy.

Member Function Documentation

◆ allocate()

pointer pmem::obj::standard_alloc_policy< void >::allocate ( size_type  cnt,
const_pointer  = 0 
)
inline

Allocate storage for cnt bytes.

Assumes sizeof(void) = 1.

Parameters
[in]cntthe number of bytes to be allocated.
Exceptions
transaction_scope_errorif called outside of a transaction.

◆ deallocate()

void pmem::obj::standard_alloc_policy< void >::deallocate ( pointer  p,
size_type  = 0 
)
inline

Deallocates storage pointed to p, which must be a value returned by a previous call to allocate that has not been invalidated by an intervening call to deallocate.

Parameters
[in]ppointer to the memory to be deallocated.

◆ max_size()

size_type pmem::obj::standard_alloc_policy< void >::max_size ( ) const
inline

The largest value that can meaningfully be passed to allocate().

Returns
largest value that can be passed to allocate.
