Elliott Hughes 17a8b0db63 Expose wait4 as wait4 rather than __wait4. 
This helps strace(1) compile with one fewer hack.

Raw Blame History

# 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/_unistd.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, MIPS use:
# return_type funcname[:syscall_name](parameters) arm_number,x86_number,mips_number
#
# This file is processed by a python script named gensyscalls.py.
#
# The checksyscalls.py script can check that the syscall numbers here are
# correct by comparing them to the numbers in the Linux kernel headers.
