Two processes X and Y need to access a critical section. Consider the following synchronization construct used by both the processes
|
Process X
/* other code for process X */
while(true)
{
varP=true;
while(varQ==true)
{
/* Critical Section */
varP=false;
}
}
/* other code for process X*/ |
Process Y
/* other code for process Y */
while(true)
{
varQ=true;
while(varP==true)
{
/* Critical Section */
varQ=false;
}
}
/* other code for process Y */ |
Here, varP and varQ are shared variables and both are initialized to false. Which one of the following statements is true?
