This was the original rationale for creating cookies and in general storing web content on the client side.
First. let me help you clarify.

Cookies are generally not "queried" by a server. Cookies are sent to the server with each page (that belong to the same cookie domain) as part of the standard HTTP request.

If you open any web dev tool, like Google Chrome Web Dev Tools (but it is the same with each major browser), you will see the cookies are sent with each page, not requested by the server.

Sorry, I just wanted to be technically correct.
 
volmgt_running(3VOLMGT) 				Volume Management Library Functions				   volmgt_running(3VOLMGT)

NAME
volmgt_running - return whether or not volume management is running SYNOPSIS
cc [ flag ... ] file ... -lvolmgt [ library ... ] #include <volmgt.h> int volmgt_running(void); DESCRIPTION
This function is obsolete. The management of removable media by the Volume Management feature, including vold, has been replaced by soft- ware that supports the Hardware Abstraction Layer (HAL). Programmatic support for HAL is through the HAL APIs, which are documented on the HAL web site. See hal(5). volmgt_running() tells whether or not Volume Management is running. RETURN VALUES
volmgt_running() always returns 0 indicating Volume Management (as implemented by vold) is not running. ERRORS
volmgt_running() will fail, returning 0, if a stat(2) or open(2) of /dev/volctl fails, or if any of the following is true: ENXIO Volume Management is not running. EINTR An interrupt signal was detected while checking to see if Volume Management was running. EXAMPLES
Example 1 Using volmgt_running() To see if Volume Management is running: if (volmgt_running() != 0) { (void) printf("Volume Management is running "); } else { (void) printf("Volume Management is NOT running "); } ATTRIBUTES
