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). 32 #
