1# this file is used to list all the syscalls that will be supported by 2# the Bionic C library. It is used to automatically generate the syscall 3# stubs, the list of syscall constants (__NR_xxxx) and the content of <linux/_unitsd.h> 4# 5# each non comment line has the following format: 6# 7# return_type func_name[:syscall_name[:call_id]]([parameter_list]) (#syscall_number|stub) 8# 9# note that: 10# - syscall_name correspond to the name of the syscall, which may differ from 11# the exported function name (example: the exit syscall is implemented by the _exit() 12# function, which is not the same as the standard C exit() function which calls it) 13# The call_id parameter, given that func_name and syscall_name have 14# been provided, allows the user to specify dispatch style syscalls. 15# For example, socket() syscall on i386 actually becomes: 16# socketcall(__NR_socket, 1, *(rest of args on stack)). 17# 18# - each parameter type is assumed to be stored on 32 bits, there is no plan to support 19# 64-bit architectures at the moment 20# 21# - it there is "stub" instead of a syscall number, the tool will not generate any 22# assembler template for the syscall; it's up to the bionic implementation to provide 23# a relevant C stub 24# 25# - additionally, if the syscall number is different amoung ARM, x86 and SuperH, use: 26# return_type funcname[:syscall_name](parameters) arm_number,x86_number,superh_number 27# 28# the file is processed by a python script named
