PetscIntSumError#
Computes the sum of two positive PetscInt and generates an error with overflow.
Synopsis#
static inline PetscErrorCode PetscIntSumError(PetscInt a, PetscInt b, PetscInt *result)
Not Collective; No Fortran Support
Input Parameters#
- a - the - PetscIntvalue
- b - the second value 
Output Parameter#
- c - the result as a - PetscIntvalue, or- NULLif you do not want the result, you just want to check if it overflows
Notes#
Use PetscInt64Mult() to compute the product of two 32-bit PetscInt and store in a PetscInt64
Use PetscIntMultTruncate() to compute the product of two PetscInt and truncate it to fit in a PetscInt
