# 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/_unitsd.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, x86 and SuperH, use: # return_type funcname[:syscall_name](parameters) arm_number,x86_number,superh_number #
