standard.lib.shared.share_open

Name Version Deprecated
share_open version 1.0 no

Prototype:
number share_open(number key[, boolean bReadOnly=false])

Parameters:
key      the key used to identify the shared memory segment
bReadOnly      true if the segment cannot be written

Description:
Accesses a previously created shared memory segment. The segment identified by key must exist; you can create shared memory segments with share_create.

Example: 
import standard.lib.shared



class Main {

	function Main() {

		var ctx=share_open(123);

		echo ctx;

		share_lock(ctx);

		for (var i=0;i<200000;i++) {

			share_set(ctx,""+i);

		}

		echo "done lock";

		echo "SH:"+share_unlock(ctx)+"\n";

		echo "SH:"+share_unlock(ctx)+"\n";

		echo share_get(ctx);

		echo "\n";

		echo typeof this;

		while (1) {

			echo ""+share_link_count(ctx)+"\r";

		}

	}

}

Returns:
Returns a shared memory handle. If failed, a run time error is raised. For controlling run-time errors you should set at the beginning of your program: pragma lib_exceptions on
