1# This file is used to automatically generate bionic's system call stubs.
3# Each non-blank, non-comment line has the following format:
5# return_type func_name[|alias_list][:syscall_name[:socketcall_id]]([parameter_list]) arch_list
7# where:
8#       arch_list ::= "all" | arch+
9#       arch      ::= "arm" | "arm64" | "mips" | "mips64" | "x86" | "x86_64"
11# Note:
12#      - syscall_name corresponds to the name of the syscall, which may differ from
13#        the exported function name (example: the exit syscall is implemented by the _exit()
14#        function, which is not the same as the standard C exit() function which calls it)
16#      - alias_list is optional comma separated list of function aliases.
18#      - The call_id parameter, given that func_name and syscall_name have
19#        been provided, allows the user to specify dispatch style syscalls.
20#        For example, socket() syscall on i386 actually becomes:
21#          socketcall(__NR_socket, 1, *(rest of args on stack)).
23#      - Each parameter type is assumed to be stored in 32 bits.
