# <http://www.gnu.org/software/libc/>
## Sources
For concenience, we maintain our own [[source
repository|source_repositories/glibc]].
# Specifics
## Ports
Porting glibc to a specific architecture is non-trivial.
The main port is x86, which is somewhat complete and is maintained. There were
incomplete ports for Alpha, MIPS, and PowerPC, but they were unmaintained and
have been removed.
## [[Hurd-specific Port|hurd/glibc]]
An important part of the [[Hurd]] actually resides in glibc: here, the system
interfaces are implemented on top of the [[Hurd IPC protocols|hurd/interface]].
This is different to the Linux port, where most simple system interfaces are in
fact simply forwarded to/implemented as [[system_call]]s.
## [[Maintenance|open_issues/glibc]]
# Implementation Details
* [[hurd/glibc/Hurd-specific API]]
* [[open_issues/secure_file_descriptor_handling]]
* [[signal/signal_thread]]
* [[startup]]
## Concepts
* [[environment_variable]]
* [[file_descriptor]]
* [[process]]
* [[signal]]
* [[ioctl]]
## Individual functions
Some of these are well-known as [[UNIX]] [[system call]]s.
* [[fallocate]]
* [[fork]]
* [[mmap]]
* [[poll]]
# Debugging
Some hints for [[debugging]].
