NAME

ACE_Handle_Gobbler - This class gobbles up handles.

SYNOPSIS

#include <ace/Handle_Gobbler.h>
class ACE_Handle_Gobbler
{
  public:
    inline ~ACE_Handle_Gobbler (void);
    inline int consume_handles (size_t n_handles_to_keep_available);
    inline int free_handles (size_t n_handles);
    inline void close_remaining_handles (void);
  private:
    typedef ACE_Unbounded_Set<ACE_HANDLE> HANDLE_SET;
    HANDLE_SET handle_set_;
};

DESCRIPTION

This is useful when we need to control the number of handles available for a process. This class is mostly used for testing purposes.

PUBLIC MEMBERS

inline ~ACE_Handle_Gobbler (void);

Destructor. Cleans up any remaining handles.

inline int consume_handles (size_t n_handles_to_keep_available);

Handles are opened continously until the process runs out of them, and then n_handles_to_keep_available handles are closed (freed) thereby making them usable in the future.

inline int free_handles (size_t n_handles);

Free up n_handles.

inline void close_remaining_handles (void);

All remaining handles are closed.

PRIVATE MEMBERS

typedef ACE_Unbounded_Set<ACE_HANDLE> HANDLE_SET;


HANDLE_SET handle_set_;

The container which holds the open descriptors.
