(since C++20) | |
Deallocates the storage pointed to by p , which must have been allocated from a std::pmr::memory_resource x that compares equal to * resource ( ) , using x. allocate ( nbytes, alignment ) , typically through a call to allocate_bytes ( nbytes, alignment ) .
Equivalent to resource ( ) - > deallocate ( p, nbytes, alignment ) ; .
Parameters
p | - | pointer to memory to deallocate |
nbytes | - | the number of bytes originally allocated |
alignment | - | the alignment originally allocated |
Exceptions
Throws nothing.
Notes
This function was introduced for use with the fully-specialized allocator std:: pmr :: polymorphic_allocator <> , but it may be useful in any specialization.
