I know that SIGCONT continues a process previously stopped by SIGSTOP. Can I use SIGCONT multiple times without a SIGSTOP ? i,e , below sequence is valid ?
SIGSTOP to process A : The process stops
SIGCONT to process A : Process resumes
SIGCONT to process A : Process already runs - this SIGCONT has no effect
SIGCONT to process A : Process already runs - this SIGCONT has no effect
...
SIGSTOP to process A : The process stops
SIGCONT to process A : Process resumes
