# PetscCuBLASIntCast

like `PetscBLASIntCast()`, but for `PetscCuBLASInt`.

## Synopsis

    static inline PetscErrorCode PetscCuBLASIntCast(MPIU_Count a, PetscCuBLASInt *b)

Not Collective; No Fortran Support

## Input Parameter

- a - the `PetscInt` value

## Output Parameter

- b - the resulting `PetscCuBLASInt` value, or `NULL` if the result is not needed

## Note

Errors if the integer is negative since PETSc calls to cuBLAS and friends never need to cast negative integer inputs
