NAME

libcres.a - a subset of functions from libc.a

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 HPUX 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.
