The Linux Standard Base (LSB) defines a system interface for compiled
applications and a minimal environment for support of installation scripts. Its
purpose is to enable a uniform industry standard environment for high-volume
applications conforming to the LSB.
These specifications are composed of two basic parts: a common part describing
those parts of the interface that remain constant across all implementations of the
LSB, and an architecture-specific part describing the parts of the interface that
vary by processor architecture. Together, the common part and the relevant
architecture-specific part for a single hardware architecture provide a complete
interface specification for compiled application programs on systems that share
a common hardware architecture.
The LSB contains both a set of Application Program Interfaces (APIs) and
Application Binary Interfaces (ABIs). APIs may appear in the source code of
portable applications, while the compiled binary of that application may use the
larger set of ABIs. A conforming implementation provides all of the ABIs listed
here. The compilation system may replace (e.g. by macro definition) certain APIs
with calls to one or more of the underlying binary interfaces, and may insert calls
to binary interfaces as needed.
The LSB is primarily a binary interface definition. Not all of the source level APIs
available to applications may be contained in this specification.
This is the common part of the Core module of the Linux Standard Base (LSB),
LSB Core - Generic. This module provides the fundamental system interfaces,
libraries, and runtime environment upon which all conforming applications and
libraries depend.
LSB Core - Generic, the common part, should be used in conjunction with an
architecture-specific part. Whenever a section of the common part is
supplemented by architecture-specific information, the common part includes a
reference to the architecture-specific part. Architecture-specific parts of the LSB
Core Specification may also contain additional information that is not referenced
in the common part.
Interfaces described in this part of the LSB Core Specification are mandatory
except where explicitly listed otherwise. Interfaces described in the LSB Core
module are supplemented by other LSB modules. All other modules depend on
the presence of LSB Core.
