如何获得Linux系统调用的列表和它们自动执行的args数量?

I writing a Linux system call map for the radare2 debugger. This means providing a huge static array mapping system call number to a syscall name name and the number of arguments it takes. This was easy for OpenBSD as the syscall numbers are defined in sys/syscall.h and in a comment above each is the number of args. It was just a matter of writing a script to parse this and throw out the C code for the array.I writing a Linux system call map for the radar
