# libos-i.tex   [plain text]

The operating-system specific functions provide an interface between the
other parts of the \libname{libkrb5.a} libraries and the operating system.

Beware! Any of the functions below are allowed to be implemented as
macros.  Prototypes for functions can be found in {\tt
<krb5/libos-proto.h>}; other definitions (including macros, if used) are
in {\tt <krb5/libos.h>}.

The following global symbols are provided in \libname{libos.a}.  If you
wish to substitute for any of them, you must substitute for all of them
(they are all declared and initialized in the same object file):
\begin{description}
