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.
