| # this file is used to list all the syscalls that will be supported by |
| # the Bionic C library. It is used to automatically generate the syscall |
| # stubs, the list of syscall constants (__NR_xxxx) and the content of <linux/_unistd.h> |
| # |
| # each non comment line has the following format: |
| # |
| # return_type func_name[:syscall_name[:call_id]]([parameter_list]) (syscall_number|"stub") |
| # |
| # note that: |
| # - syscall_name correspond to the name of the syscall, which may differ from |
| # the exported function name (example: the exit syscall is implemented by the _exit() |
| # function, which is not the same as the standard C exit() function which calls it) |
| # The call_id parameter, given that func_name and syscall_name have |
| # been provided, allows the user to specify dispatch style syscalls. |
| # For example, socket() syscall on i386 actually becomes: |
| # socketcall(__NR_socket, 1, *(rest of args on stack)). |
| # |
| # - each parameter type is assumed to be stored on 32 bits, there is no plan to support |
| # 64-bit architectures at the moment |
| # |
| # - it there is "stub" instead of a syscall number, the tool will not generate any |
| # assembler template for the syscall; it's up to the bionic implementation to provide |
| # a relevant C stub |
| # |
| # - additionally, if the syscall number is different amoung ARM, and x86, MIPS use: |
| # return_type funcname[:syscall_name](parameters) arm_number,x86_number,mips_number |
| # |
| # This file is processed by a python script named gensyscalls.py. |
| # |
| # The checksyscalls.py script can check that the syscall numbers here are |
| # correct by comparing them to the numbers in the Linux kernel headers. |
