+# 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
