Bionic is a very small C library because we have decided to *not* implement various features
of the POSIX standard. we only add functions on a as-needed basis, and there are a few things
we wish we'll never put in there.
this file is here to document explicitely what we don't want to support in Bionic:
- C++ exceptions are not supported. on embedded systems, they lead to extremely larger and
slower code for no good reason (even when so-called zero-cost exception schemes are
implemented, they enforce very large numbers of registers spills to the stack, even
in functions that do not throw an exception themselves).
- pthread cancellation is *not* supported. this seemingly simple "feature" is the source
of much bloat and complexity in a C library. Besides, you'd better write correct
multi-threaded code instead of relying on this stuff.
- pthread_once() doesn't support C++ exceptions thrown from the init function, or the init
function doing a fork().
- locales and wide characters are not supported. we use ICU for all this i18n stuff, which
is much better than the ill-designed related C libraries functions.
- at the moment, several user-account-related functions like getpwd are stubbed and return
the values corresponding to root. this will be fixed when we'll be able to have distinct
users on the Android filesystem. :-(
see bionic/stubs.c for the details

Welcome to Bionic, Android small and custom C library for the Android platform
Bionic is mainly a port of the BSD C library to our Linux kernel with the
following additions/changes:
- no support for locales
- no support for wide chars (i.e. multi-byte characters)
- its own smallish implementation of pthreads based on Linux futexes
- support for x86, ARM and ARM thumb CPU instruction sets and kernel interfaces
Bionic is released under the standard 3-clause BSD License
Bionic doesn't want to implement all features of a traditional C library, we only
add features to it as we need them, and we try to keep things as simple and small
as possible. Our goal is not to support scaling to thousands of concurrent threads
on multi-processors machines; we're running this on cell-phones, damnit !!
Note that Bionic doesn't provide a libthread_db or a libm implementation.
Adding new syscalls:
====================
Bionic provides the gensyscalls.py Python script to automatically generate syscall
stubs from the list defined in the file SYSCALLS.TXT. You can thus add a new syscall
by doing the following:
- edit SYSCALLS.TXT
- add a new line describing your syscall, it should look like:
return_type syscall_name(parameters) syscall_number
- in the event where you want to differentiate the syscall function from its entry name,
use the alternate:
return_type funcname:syscall_name(parameters) syscall_number
- additionally, if the syscall number is different between ARM and x86, use:
return_type funcname[:syscall_name](parameters) arm_number,x86_number
- a syscall number can be -1 to indicate that the syscall is not implemented on
a given platform, for example:
void __set_tls(void*) arm_number,-1
the comments in SYSCALLS.TXT contain more information about the line format
You can also use the 'checksyscalls.py' script to check that all the syscall
numbers you entered are correct. It does so by looking at the values defined in
your Linux kernel headers. The script indicates where the values are incorrect
and what is expected instead.

# 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/_unitsd.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
#
# the file is processed by a python script named gensyscalls.py
