142:   PetscDefined - determine whether a boolean macro is defined

144:   Notes:
145:   The prefix "PETSC_" is added to the argument.

147:   Typical usage is within normal code,

149: $   if (PetscDefined(USE_DEBUG)) { ... }

151:   but can also be used in the preprocessor,

153: $   #if PetscDefined(USE_DEBUG)
154: $     ...
155: $   #else

157:   Either way, it evaluates true if PETSC_USE_DEBUG is defined (merely defined or defined to 1), and false if PETSC_USE_DEBUG is undefined.  This macro
158:   should not be used if its argument may be defined to a non-empty value other than 1.

160:   To avoid prepending "PETSC_", say to add custom checks in user code, one can use e.g.

162: $  #define FooDefined(d) PetscDefined_(FOO_ ## d)

164:   Developer Notes:
165:   Getting something that works in C and CPP for an arg that may or may not be defined is tricky.  Here, if we have
166:   "#define PETSC_HAVE_BOOGER 1" we match on the placeholder define, insert the "0," for arg1 and generate the triplet
167:   (0, 1, 0).  Then the last step cherry picks the 2nd arg (a one).  When PETSC_HAVE_BOOGER is not defined, we generate
168:   a (... 1, 0) pair, and when the last step cherry picks the 2nd arg, we get a zero.

170:   Our extra expansion via PetscDefined__take_second_expand() is needed with MSVC, which has a nonconforming

1953: -  PETSC_PREFETCH_HINT_T2 - Fetch to high-level cache only.  (On many systems, T0 and T1 are equivalent.)

2368:     PETSC_VERSION - This manual page provides information about how PETSc documents and uses its version information. This information is available to both C/C++
2369:                     and Fortran compilers when petscsys.h is included.


2372:     The current PETSc version and the API for accessing it are defined in petscversion.h

2374:     The complete version number is given as the triple  PETSC_VERSION_MAJOR.PETSC_VERSION_MINOR.PETSC_VERSION_SUBMINOR (in short hand x.y.z)

2376:     A change in the minor version number (y) indicates possible/likely changes in the PETSc API. Note this is different than with the semantic versioning convention
2377:     where only a change in the major version number (x) indicates a change in the API.

2379:     A subminor greater than zero indicates a patch release. Version x.y.z maintains source and binary compatibility with version x.y.w for all z and w

2381:     Use the macros PETSC_VERSION_EQ(x,y,z), PETSC_VERSION_LT(x,y,z), PETSC_VERSION_LE(x,y,z), PETSC_VERSION_GT(x,y,z),
2382:     PETSC_VERSION_GE(x,y,z) to determine if the current version is equal to, less than, less than or equal to, greater than or greater than or equal to a given
2383:     version number (x.y.z).

2385:     PETSC_RELEASE_DATE is the date the x.y version was released (i.e. the version before any patch releases)

2387:     PETSC_VERSION_DATE is the date the x.y.z version was released

2389:     PETSC_VERSION_GIT is the last git commit to the repository given in the form vx.y.z-wwwww

2391:     PETSC_VERSION_DATE_GIT is the date of the last git commit to the repository

2393:     Level: intermediate

2395:     PETSC_VERSION_() and PETSC_VERSION_PATCH are deprecated and will eventually be removed. For several releases PETSC_VERSION_PATCH is always 0

2401:     UsingFortran - To use PETSc with Fortran you must use both PETSc include files and modules. At the beginning
2402:       of every function and module definition you need something like

2406: $         use petscXXX

2408:      You can declare PETSc variables using either of the following.
