TAU_REGISTER_FORK(3)					      TAU Instrumentation API					      TAU_REGISTER_FORK(3)

NAME
       TAU_REGISTER_FORK - Informs the measurement system that a fork has taken place

SYNOPSIS
       C/C++:

       TAU_REGISTER_FORK(int pid, enum TauFork_t option);

DESCRIPTION
       To register a child process obtained from the fork() syscall, invoke the TAU_REGISTER_FORK macro. It takes two parameters, the first is the
       node id of the child process (typically the process id returned by the fork call or any 0..N-1 range integer). The second parameter
       specifies whether the performance data for the child process should be derived from the parent at the time of fork (
       TAU_INCLUDE_PARENT_DATA ) or should be independent of its parent at the time of fork ( TAU_EXCLUDE_PARENT_DATA ). If the process id is used
       as the node id, before any analysis is done, all profile files should be converted to contiguous node numbers (from 0..N-1). It is highly
       recommended to use flat contiguous node numbers in this call for profiling and tracing.

EXAMPLE
       C/C++ :

       pID = fork();
       if (pID == 0) {
	 printf("Parent : pid returned %d
", pID)
       }  else {
	 // If we'd used the TAU_INCLUDE_PARENT_DATA, we get
	 // the performance data from the parent in this process
	 // as well.
	 TAU_REGISTER_FORK(pID, TAU_EXCLUDE_PARENT_DATA);
	 printf("Child : pid = %d", pID);
       }
