1# this file is used to list all the syscalls that will be supported by
2# the Bionic C library. It is used to automatically generate the syscall
3# stubs, the list of syscall constants (__NR_xxxx) and the content of <linux/_unitsd.h>
4#
5# each non comment line has the following format:
6#
7# return_type    func_name[:syscall_name[:call_id]]([parameter_list])  (#syscall_number|stub)
8#
9# note that:
10#      - syscall_name correspond to the name of the syscall, which may differ from
11#        the exported function name (example: the exit syscall is implemented by the _exit()
12#        function, which is not the same as the standard C exit() function which calls it)
13#        The call_id parameter, given that func_name and syscall_name have
14#        been provided, allows the user to specify dispatch style syscalls.
15#        For example, socket() syscall on i386 actually becomes:
16#          socketcall(__NR_socket, 1, *(rest of args on stack)).
17#
18#      - each parameter type is assumed to be stored on 32 bits, there is no plan to support
19#        64-bit architectures at the moment
20#
21#      - it there is "stub" instead of a syscall number, the tool will not generate any
22#        assembler template for the syscall; it's up to the bionic implementation to provide
23#        a relevant C stub
24#
25#      - additionally, if the syscall number is different amoung ARM, x86 and SuperH, use:
26#        return_type funcname[:syscall_name](parameters) arm_number,x86_number,superh_number
27#
