Open an Existing Shared Object by Path

Opens a shared object that was created by another process. This is useful for workers that need to attach to shared data without having the original shard_shared object.

Usage

share_open(path, backing = c("mmap", "shm"), size = NULL)

Arguments

path

Path to the shared segment.

backing

Backing type: "mmap" or "shm".

size

Size of the segment in bytes. If NULL, attempts to detect.

Value

A shard_shared object attached to the existing segment.

Examples

# \donttest{
shared <- share(1:50)
info <- shared_info(shared)
reopened <- share_open(info$path, backing = "mmap")
close(reopened)
close(shared)
# }
