#include <Memory_Pool.h>

List of all members.

Public Methods

 ACE_MMAP_Memory_Pool_Options (const void *base_addr = ACE_DEFAULT_BASE_ADDR, int use_fixed_addr = 1, int write_each_page = 1, off_t minimum_bytes = 0, u_int flags = 0, int guess_on_fault = 1, LPSECURITY_ATTRIBUTES sa = 0)

Public Attributes

const void* base_addr_
 Base address of the memory-mapped backing store.

int use_fixed_addr_
 Must we use the <base_addr_> or can we let mmap(2) select it?

int write_each_page_
 Should each page be written eagerly to avoid surprises later on?

off_t minimum_bytes_
 What the minimim bytes of the initial segment should be.

u_int flags_
 Any special flags that need to be used for <mmap>.

int guess_on_fault_
LPSECURITY_ATTRIBUTES sa_
 Pointer to a security attributes object. Only used on NT.


Detailed Description

Helper class for MMAP Memory Pool constructor options.

This should be a nested class, but that breaks too many compilers.

Member Data Documentation

const void * ACE_MMAP_Memory_Pool_Options::base_addr_
 

Base address of the memory-mapped backing store.

u_int ACE_MMAP_Memory_Pool_Options::flags_
 

Any special flags that need to be used for <mmap>.

int ACE_MMAP_Memory_Pool_Options::guess_on_fault_
 

Try to remap without knowing the faulting address. This parameter is ignored on platforms that know the faulting address (UNIX with SI_ADDR and Win32).

off_t ACE_MMAP_Memory_Pool_Options::minimum_bytes_
 

What the minimim bytes of the initial segment should be.

LPSECURITY_ATTRIBUTES ACE_MMAP_Memory_Pool_Options::sa_
 

Pointer to a security attributes object. Only used on NT.

int ACE_MMAP_Memory_Pool_Options::use_fixed_addr_
 

Must we use the <base_addr_> or can we let mmap(2) select it?

int ACE_MMAP_Memory_Pool_Options::write_each_page_
 

Should each page be written eagerly to avoid surprises later on?
