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.
Return value:
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
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";
}
}
