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 #
