PetscBool

Logical variable. Actually an int 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.
