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.
