An LSB-conforming implementation shall support some base libraries which provide interfaces for accessing the operating system, processor and other hardware in the system.[1]

Interfaces for libc

The behaviour of the interfaces in this library is specified by the following Standards.

ISO/IEC 9899: 1999, Programming Languages --C[2]

Notes

[1]

Symbol versions are unique for each architecture. In release 1.0 of this specification, the versions for only the IA32 architecture are specified. Versions will be correctly specified on a per achitecture basis in future releases of the specification.
