SYSCALLS.TXT revision b4f7616fd618875768b8fffc122b58bdb84a9969
1# This file is used to automatically generate bionic's the system calls stubs. 2# 3# Each non comment line has the following format: 4# 5# return_type func_name[:syscall_name[:call_id]]([parameter_list]) (1|-1|"stub") 6# 7# Note that: 8# - syscall_name corresponds to the name of the syscall, which may differ from 9# the exported function name (example: the exit syscall is implemented by the _exit() 10# function, which is not the same as the standard C exit() function which calls it) 11# The call_id parameter, given that func_name and syscall_name have 12# been provided, allows the user to specify dispatch style syscalls. 13# For example, socket() syscall on i386 actually becomes: 14# socketcall(__NR_socket, 1, *(rest of args on stack)). 15# 16# - each parameter type is assumed to be stored on 32 bits, there is no plan to support 17# 64-bit architectures at the moment 18# 19# - the final field can be "1", meaning: generate a stub for each architecture, 20# taking the constants from the kernel header files. 21# 22# - the final field can be "stub" meaning: do not generate any stubs --- 23# in this case, a hand-written custom stub must be provided. 24# TODO: replace this with something like "custom" or "none", or remove 25# it entirely. 26# 27# - the final field can be a three-element list of 1s and -1 meaning: 28# this system call is only available on some of the architectures (1), 29# and no stub should be generated for those architectures marked with -1. 30# the order is arm,x86,mips. 31# TODO: replace this with something more readable like "-arm,-mips" (meaning x86 only). 32# 33# This file is processed by a python script named gensyscalls.py. 34# 35 36# process management 37void _exit:exit_group (int) 1
