Supplied ATLAS libraries and their corresponding header files

Note: In the subsequent names, replace * with any specific name (specific header file name or library file name).

The following main libraries are provided with ATLAS.

ATLAS main library

ATLAS main library contains ATLAS specific variants of the BLAS, CBLAS, and LAPACK routines.

Notes:

For each of the above mentioned base libraries, the single-threaded and multi-threaded versions of the same base library contain the same list of functions.
Only static libraries are provided.
The libraries will archive 31-bit C linkage, 31-bit XPLink C linkage, and 64-bit C linkage objects. The linker, based on supplied options and/or environment variables will choose the appropriate archive members of specified libraries.
