A file is to be shared among different processes, each of which has a unique number. The file can be accessed simultaneously by several processes, subject to the following constraint: The process priority must be lower than or equal to the priority numbers all of the other processes currently accessing the file.

Using pseudocode (see below), write a monitor to coordinate access to the file.

A basic monitor is set up as follows:

Monitor name {

//shared variables

REQUESTprocedure ( ){}

RELEASEprocedure ( ){}

. . . //initializtion code( ){ }

}
