# 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, and x86, use:
#        return_type funcname[:syscall_name](parameters) arm_number,x86_number
#
# the file is processed by a python script named gensyscalls.py
