|
The %{name} package provides the "libffi" library at version 3.1
|
|
which provides the shared object (SONAME) "libffi.so.6" for all
|
|
objects that require that library version. This is a compatibility
|
|
library and packages should be compiling against the latest version
|
|
of the "libffi" library using the libffi-devel (not %{name})
|
|
package.
|
|
|
|
Compilers for high level languages generate code that follow certain
|
|
conventions. These conventions are necessary, in part, for separate
|
|
compilation to work. One such convention is the "calling convention".
|
|
The calling convention is a set of assumptions made by the compiler
|
|
about where function arguments will be found on entry to a function. A
|
|
calling convention also specifies where the return value for a function
|
|
is found.
|
|
|
|
Some programs may not know at the time of compilation what arguments
|
|
are to be passed to a function. For instance, an interpreter may be
|
|
told at run-time about the number and types of arguments used to call a
|
|
given function. `Libffi' can be used in such programs to provide a
|
|
bridge from the interpreter program to compiled code.
|
|
|
|
The `libffi' library provides a portable, high level programming
|
|
interface to various calling conventions. This allows a programmer to
|
|
call any function specified by a call interface description at run time.
|
|
|
|
FFI stands for Foreign Function Interface. A foreign function
|
|
interface is the popular name for the interface that allows code
|
|
written in one language to call code written in another language. The
|
|
`libffi' library really only provides the lowest, machine dependent
|
|
layer of a fully featured foreign function interface. A layer must
|
|
exist above `libffi' that handles type conversions for values passed
|
|
between the two languages.
