PetscFPrintf#
Prints to a file, only from the first MPI process in the communicator.
Synopsis#
PetscErrorCode PetscFPrintf(MPI_Comm comm, FILE *fd, const char format[], ...)
Not Collective
Input Parameters#
comm - the MPI communicator
fd - the file pointer,
PETSC_STDOUTor value obtained fromPetscFOpen()format - the usual
printf()format string
Fortran Note#
The call sequence is PetscFPrintf(MPI_Comm, fp, character(*), PetscErrorCode ierr).
That is, you can only pass a single character string from Fortran.
Developer Notes#
This maybe, and is, called from PETSc error handlers and PetscMallocValidate() hence it does not use PetscCallMPI() which
could recursively restart the malloc validation.
