NAME

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

DESCRIPTION

The libcres.a library is an archive library that has functions that do not call other functions or they do

not use shared data. The intent of this library is to provide a static link for API’s that are performance criti-

cal applications. Linking statically with

libc is not a supported method of linking an application. Any

performance improvement is highly dependent on the application’s use of the included functions. It is

recommended that the application performance be measured before deciding on this link method.

The

libcres.a library can be linked with an application with the use of the

-l:libcres.a syntax as

documented in

ld (see ld(1)).

The contents of this library, as listed below, can and may change in future releases or patches. If a function

is removed from this library, applications that are currently linked will not be affected and when re-linked,

they will get the affected function from

libc.sl. If a new function is added to libcres.a, currently

linked applications will not be affected. However, the application will bind the new function from

libcres.a instead of the same function in

libc.sl.

The current interfaces in

libcres.a are listed below:

abs(), bsearch(), div(), ffs(), insque(), labs(), ldiv(), memchr(), memcmp()

memcpy(), memmove(), memset(), strcat(), strchr(), strcmp(), strcpy(),

strcspn(), strlen(), strncat() , strncmp() , strncpy() , strrchr(), strspn(),

strstr(), swab().

WARNINGS

The above functions can not be overridden with a user-deﬁned function of the same name (as is the case

today with libc names). The user must refrain from using these names or unexpected results may occur.
