## NAME

ACE_Shared_Memory - This base class adapts both System V shared memory and "BSD" mmap to a common API.

## SYNOPSIS

    #include <ace/Shared_Memory.h>

    class ACE_Shared_Memory
    {
      public:
        virtual ~ACE_Shared_Memory (void);
        virtual int close (void) = 0;
        virtual int remove (void) = 0;
        virtual void *malloc (size_t = 0) = 0;
        virtual int free (void *p) = 0;
        virtual int get_segment_size (void) const = 0;
        virtual ACE_HANDLE get_id (void) const = 0;
    };

## DESCRIPTION

This is a very simple-minded wrapper, i.e., it really is only useful for allocating large contiguous chunks of shared memory. For a much more sophisticated version, please check out the `ACE_Malloc` class.

## Note that all the following methods are pure virtual.

    virtual int close (void) = 0;

    virtual int remove (void) = 0;

    virtual void *malloc (size_t = 0) = 0;

    virtual int free (void *p) = 0;

    virtual int get_segment_size (void) const = 0;

    virtual ACE_HANDLE get_id (void) const = 0;
