5 /* Configuration file for SuiteSparse: a Suite of Sparse matrix packages
6  * (AMD, COLAMD, CCOLAMD, CAMD, CHOLMOD, UMFPACK, CXSparse, and others).
7  *
8  * SuiteSparse_config.h provides the definition of the long integer. On most
9  * systems, a C program can be compiled in LP64 mode, in which long's and
10  * pointers are both 64-bits, and int's are 32-bits. Windows 64, however, uses
11  * the LLP64 model, in which int's and long's are 32-bits, and long long's and
12  * pointers are 64-bits.
13  *
14  * SuiteSparse packages that include long integer versions are
15  * intended for the LP64 mode. However, as a workaround for Windows 64
16  * (and perhaps other systems), the long integer can be redefined.
17  *
18  * If _WIN64 is defined, then the __int64 type is used instead of long.
19  *
20  * The long integer can also be defined at compile time. For example, this
21  * could be added to SuiteSparse_config.mk:
22  *
23  * CFLAGS = -O -D'SuiteSparse_long=long long' \
24  * -D'SuiteSparse_long_max=9223372036854775801' -D'SuiteSparse_long_idd="lld"'
25  *
26  * This file defines SuiteSparse_long as either long (on all but _WIN64) or
27  * __int64 on Windows 64. The intent is that a SuiteSparse_long is always a
28  * 64-bit integer in a 64-bit code. ptrdiff_t might be a better choice than
29  * long; it is always the same size as a pointer.
30  *
31  * This file also defines the SUITESPARSE_VERSION and related definitions.
