Overview

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

Initialization method.

ACE_Shared_Memory_Pool_Options (
    const char *base_addr = ACE_DEFAULT_BASE_ADDR,
    size_t max_segments = ACE_DEFAULT_MAX_SEGMENTS,
    size_t file_perms = ACE_DEFAULT_FILE_PERMS,
    off_t minimum_bytes = 0,
    size_t segment_size = ACE_DEFAULT_SEGMENT_SIZE
    );

const char *base_addr_;

Base address of the memory-mapped backing store.

size_t max_segments_;

Number of shared memory segments to allocate.

off_t minimum_bytes_;

What the minimum bytes of the initial segment should be.

size_t file_perms_;

File permissions to use when creating/opening a segment.

size_t segment_size_;

Shared memory segment size.
