Detailed Description

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]

cnt

the number of bytes to be allocated.

Exceptions

transaction_scope_error

if 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]

p

pointer 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.
