The decrease count [] function in the previous exercise currently returns 0 if sufficient resources are available and −1 otherwise. This leads to awkward programming for a process that wishes to obtain a number of resources: while [decease_count[count] == -1] ; Rewrite the resource-manager code segment using a monitor and condition variables so that the decrease count[] function suspends the process until sufficient resources are available. This will allow a process to invoke decrease_count [] by simply calling decrease_count [count] ; The process will return from this function call only when sufficient resources are available.
