# This file is used to automatically generate bionic's system call stubs.
#
# Each non-blank, non-comment line has the following format:
#
# return_type func_name[|alias_list][:syscall_name[:socketcall_id]]([parameter_list]) arch_list
#
# where:
# arch_list ::= "all" | arches
# arches ::= arch | arch "," arches
# arch ::= "arm" | "arm64" | "x86" | "x86_64" | "lp32" | "lp64"
#
# Note:
# - syscall_name corresponds 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)
#
# - alias_list is optional comma separated list of function aliases.
#
# - 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 in 32 bits.
#
# This file is processed by a python script named gensyscalls.py, run via
# genrules in Android.bp.
