      1 # This file is used to automatically generate bionic's the system calls stubs.
      2 #
      3 # Each non comment line has the following format:
      4 #
      5 # return_type    func_name[:syscall_name[:call_id]]([parameter_list])  (1|-1|"stub")
      6 #
      7 # Note that:
      8 #      - syscall_name corresponds to the name of the syscall, which may differ from
      9 #        the exported function name (example: the exit syscall is implemented by the _exit()
     10 #        function, which is not the same as the standard C exit() function which calls it)
     11 #        The call_id parameter, given that func_name and syscall_name have
     12 #        been provided, allows the user to specify dispatch style syscalls.
     13 #        For example, socket() syscall on i386 actually becomes:
     14 #          socketcall(__NR_socket, 1, *(rest of args on stack)).
     15 #
     16 #      - each parameter type is assumed to be stored on 32 bits, there is no plan to support
     17 #        64-bit architectures at the moment
     18 #
     19 #      - the final field can be "1", meaning: generate a stub for each architecture,
     20 #        taking the constants from the kernel header files.
     21 #
     22 #      - the final field can be "stub" meaning: do not generate any stubs ---
     23 #        in this case, a hand-written custom stub must be provided.
     24 #        TODO: replace this with something like "custom" or "none", or remove
     25 #        it entirely.
     26 #
     27 #      - the final field can be a three-element list of 1s and -1 meaning:
     28 #        this system call is only available on some of the architectures (1),
     29 #        and no stub should be generated for those architectures marked with -1.
     30 #        the order is arm,x86,mips.
     31 #        TODO: replace this with something more readable like "-arm,-mips" (meaning x86 only).
