getsid - get the session ID of a process


getsid() returns the session ID of the process specified in pid. If pid is zero, the call applies to the calling process. If pid is not a member of the current session, getsid() returns -1 and sets errno to ESRCH. The current session ID is determined by a call to getsid() for the process specified in pid equal to 0.


  • pid:pid_t - the PID of the process whose session ID will be returned.

Example Use Case

Example of a use case for getsid would be implementing a process that replaces the current session's leader process with a new one, or getting the PID and session ID of newly created processes to ensure they were not orphaned.


It needs to be monitored carefully when using getsid() on processes that do not belong to the calling process’s session in order to prevent malicious actions such as hijacking of processes running in different sessions.
