And syscall are very well documented. For android, the list is perhaps here (for example): https://github.com/android/platform_bionic/blob/master/libc/SYSCALLS.TXT For interprocess/threads communication, kill() and tgkill() can be used. So perhaps for your case, tgkill() can be used for sending signals from one process to a specific thread in another process. http://linux.die.net/man/2/tgkill http://stackoverflow.com/questions/5374960/cant-compile-a-program-that-calls-tgkill ("no wrapper in glibc" is applicable to Linux, for Android, not sure if bionic is provided, but if not, just use ARM assembly ("swi") to make the syscall: http://peterdn.com/post/e28098Hello-World!e28099-in-ARM-assembly.aspx > > Thank you, > Alex > > -- > You received this message because you are subscribed to the Google > Groups "Android Developers" group. > To post to this group, send email to [email protected] > To unsubscribe from this group, send email to > [email protected] > For more options, visit this group at > http://groups.google.com/group/android-developers?hl=en > --- > You received this message because you are subscribed to the Google Groups > "Android Developers" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to [email protected]. > For more options, visit https://groups.google.com/d/optout. > -- Regards, Peter Teoh -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
