I need to do the syscalls from kernel space. Basically I am porting our custom vxWorks driver to Linux. We want to basically keep the structure of the vxWorks driver the same, so I am porting the individual vxWorks functions such as semBcreate, semGive etc. Thats why I want to use the SysV IPC semaphores, as they seem to most closely resemble the vxWorks ones. I know that there are much better ways of writing a driver, but that wouldn't fit in with the currect structure we have at the moment.
Now if I want to call lets say sys_semget() from kernel space, must I use the _syscall3() function? I saw some people using this.
Thanks for the help. Arne
