sys_semget() can be invoked with in the kernel and for that you may not need a system call table entry. However, the symbol (sys_semget()) should be usable with in the kernel. For the same you need to declare the same using EXPORT_SYMBOLS(sys_semget) in sem.h or any of the include files. For more on EXPORT_SYMBOLS() refer kernelnewbies.org or Linux Device Driver-2 by Rubini. Thanks, Sumit

But if I execute: grep -r __NR_semget /lib/modules/`uname -r`/build/include/* on my system I get this: /lib/modules/2.4.17-4GB/build/include/asm-alpha/unistd.h:#define __NR_semget205 /lib/modules/2.4.17-4GB/build/include/asm-ia64/unistd.h:#define __NR_semget1106 /lib/modules/2.4.17-4GB/build/include/asm-parisc/unistd.h:#define __NR_semget (__NR_Linux + 186) So I argue that for i386, you don't have these calls. People who know the problem better, feels free to correct me if I was wrong.
