NAME¶

std::pmr::monotonic_buffer_resource::monotonic_buffer_resource - std::pmr::monotonic_buffer_resource::monotonic_buffer_resource

Synopsis¶

monotonic_buffer_resource(); (1) (since C++17)
explicit monotonic_buffer_resource( std::pmr::memory_resource* (2) (since C++17)
upstream );
explicit monotonic_buffer_resource( std::size_t initial_size ); (3) (since C++17)
monotonic_buffer_resource( std::size_t initial_size, (4) (since C++17)
std::pmr::memory_resource* upstream );
monotonic_buffer_resource( void* buffer, std::size_t buffer_size (5) (since C++17)
);
monotonic_buffer_resource( void* buffer, std::size_t buffer_size, (6) (since C++17)
std::pmr::memory_resource* upstream );
monotonic_buffer_resource( const monotonic_buffer_resource& ) = (7) (since C++17)
delete;

Constructs a monotonic_buffer_resource. The constructors not taking an upstream
memory resource pointer use the return value of std::pmr::get_default_resource as
the upstream memory resource.

1,2) Sets the current buffer to null and the next buffer size to an
implementation-defined size.
3,4) Sets the current buffer to null and the next buffer size to a size no smaller
than initial_size.
5,6) Sets the current buffer to buffer and the next buffer size to buffer_size (but
not less than 1). Then increase the next buffer size by an implementation-defined
growth factor (which does not have to be integral).
7) Copy constructor is deleted.

Parameters¶

upstream - the upstream memory resource to use; must point to a valid memory
resource
initial_size - the minimum size of the first buffer to allocate; must be greater
than zero
buffer - the initial buffer to use
buffer_size - the size of the initial buffer; cannot be greater than the number of
bytes in buffer
