PetscBool#
Logical variable. Actually an enum in C and a logical in Fortran.
Synopsis#
typedef enum {
PETSC_FALSE,
PETSC_TRUE
} PetscBool;
Developer Note#
Why have PetscBool
, why not use bool in C? The problem is that K and R C, C99 and C++ all have different mechanisms for
boolean values. It is not easy to have a simple macro that that will work properly in all circumstances with all three mechanisms.
