TOPIC: Supported system calls

Supported system calls 9 years ago #1

hfinucane OFFLINE Posts: 2	I tried to run an application of mine under maze, but it complained that 'poll' was unsupported. I could, with a bit of work, use select() for testing only- but before I get too invested, I figured I would ask if you maintained a list of unsupported system calls.

Hi hfinucane,

Thanks a lot for reporting the problem. Indeed there are several unsupported system calls, but we can implement the support, no problem. As of today the unsupported calls are:

SYS_poll
SYS_epoll_wait
SYS_ppoll
SYS_epoll_pwait
SYS_epoll_wait_old
SYS_mq_timedsend
SYS_mq_timedreceive
SYS_rt_sigtimedwait
SYS_vfork
SYS_execve

Do you need support for the entire "poll" family, or you could name a specific call(s)?

roni OFFLINE Posts: 16	The support for poll can be added by Monday. epoll_create and epoll_ctl are fine; so is non-blocking epoll_wait (i.e. with timeout=0). How soon you will need epoll_wait? It might take a bit longer. What kind of file descriptors do yo use with epoll - pipes, sockets? Do you use the EPOLLET (edge-triggered) flag when calling epoll_ctl?

roni OFFLINE Posts: 16	I implemented support for poll system call; also for non-blocking epoll_wait. The new release 1.0-beta-2011.10.20 is ready for download. If you try to run the test case again and let us know the result, it will be of great help. Thank you in advance!
