Actually, it’s not the control of thread/process creation but the representation of those. With pthread create, user expects to give void *(*start)(void *) function pointer for thread starting point (with void* return type) and with processes there’s no entry point, but current thread of execution is forked. Also parameters are different (pid_t, status, pthread_attr_t, …)

You are welcome to point out the coding guideline faults you have seen, so I don't miss them. I will review for the variable declaration position. Regarding your other comments, wouldn't it be better to add a fifth parameter to odph_linux_odpthreads_create() like this: +int odph_linux_odpthreads_create(odph_linux_odpthread_t *thread_tbl, + const odp_cpumask_t *mask, + int (*start_routine)(void *), void *arg, + odp_thread_type_t thr_type, + odph_thread_implementation_e imp); where odph_thread_implementation_e would be an enum: { ANY (i.e. helpers decide according to command line) FORCE_PTHREAD FORCE_PROCESS } platform agnostic tests would then only be allowed to use ANY. tests on the platform side could pick what they want. And we can remove the dead code. Make sense?

There are some style / coding guideline faults (like should introduce all variables in the beginning of a code block). Also pure process and pthread helpers should remain (suggesting to leave out "helper: removing dead code"), since not all apps want to obscure whether process or pthread is used. Opaque thread type helps our purposes to test everything on both pthread and process models, but other apps are likely to care only one model. -Petri > -----Original Message----- > From: EXT
