| # This file is used to automatically generate bionic's system call stubs. |
| # |
| # It is processed by a python script named gensyscalls.py, |
| # normally run via the genrules in libc/Android.bp. |
| # |
| # Each non-blank, non-comment line has the following format: |
| # |
| # func_name[|alias_list][:syscall_name[:socketcall_id]]([parameter_list]) arch_list |
| # |
| # where: |
| # arch_list ::= "all" | arches |
| # arches ::= arch | arch "," arches |
| # arch ::= "arm" | "arm64" | "riscv64" | "x86" | "x86_64" | "lp32" | "lp64" |
| # |
| # syscall_name corresponds to the name of the syscall, which may differ from |
| # the exported function name func_name. For example: the exit_group syscall |
| # is exported by libc as the _exit() function, not exit() (which does more |
| # work before calling _exit()). |
| # |
| # alias_list is optional comma-separated list of function aliases. |
| # For example, the traditional _exit() function has a C99 alias _Exit(). |
| # |
| # No return type is specified, because it's not needed. |
| # |
| # The socketcall_id parameter supports x86's |
| # https://man7.org/linux/man-pages/man2/socketcall.2.html |
| # and can be ignored for all other syscalls and architectures. |
| # |
| # The number of registers required for the arguments is computed by the script, |
| # based on the parameter list given here. It handles the need for register |
| # pairs for 64-bit arguments on ILP32, and also arm32's requirement for such |
| # pairs to start on an even register. This means that it's important to get |
| # these types right! |
| # |
| |
| # Calls that have historical 16-bit variants camping on the best names (CONFIG_UID16). |
