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; No Fortran Support

Input Parameters#

  • comm - the MPI communicator

  • fd - the file pointer

  • format - the usual printf() format string

Developer Note#

This maybe, and is, called from PETSc error handlers and PetscMallocValidate() hence it does not use PetscCallMPI() which could recursively restart the malloc validation.
