+# 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
+#
+# the file is processed by a python script named gensyscalls.py
