libcres.a(5)

DESCRIPTION

The libcres.a library is an archive of selected functions from libc which are leaf functions that do not use shared data. This library provides applications with the ability to call those overhead-sensitive functions more efficiently than would be possible if those functions were in a shared library.

The libcres.a usage model has changed significantly for HP-UX 11i Version 1.5. In the previous HP-UX 11i release, libcres.a needs to be explicitly linked with an application by the linker option -lcres.

On the other hand, in HP-UX 11i Version 1.5, the linking with libcres.a is handled automatically when application includes the appropriate header files. It is required to include the relevant header files to take advantage of the library. When the header files are not included, libcres routines are not linked in, even if this library is explicitly linked. It is unnecessary to explicitly link the libcres.a library with an application by the linker option -lcres, though it is harmless.

WARNINGS

The contents of this library are subject to change in future releases.
