SYSCALLS.TXT revision 5386a741e77bfff4e72ca6861fdd3fe2208452ce
1# This file is used to automatically generate bionic's system call stubs. 2# 3# Each non-blank, non-comment line has the following format: 4# 5# return_type func_name[|alias_list][:syscall_name[:socketcall_id]]([parameter_list]) arch_list 6# 7# where: 8# arch_list ::= "all" | arch+ 9# arch ::= "arm" | "arm64" | "mips" | "mips64" | "x86" | "x86_64" 10# 11# Note: 12# - syscall_name corresponds to the name of the syscall, which may differ from 13# the exported function name (example: the exit syscall is implemented by the _exit() 14# function, which is not the same as the standard C exit() function which calls it) 15# 16# - alias_list is optional comma separated list of function aliases. 17# 18# - The call_id parameter, given that func_name and syscall_name have 19# been provided, allows the user to specify dispatch style syscalls. 20# For example, socket() syscall on i386 actually becomes: 21# socketcall(__NR_socket, 1, *(rest of args on stack)). 22# 23# - Each parameter type is assumed to be stored in 32 bits. 24# 25# This file is processed by a python script named gensyscalls.py. 26 27int execve(const char*, char* const*, char*
