[petsc-users] Suppress printing in PETSc

[Barry Smith]

  Bruce,

  Normally PETSc does does not print output unless you ask it, except error messages. 

  In C and C++ you can set the global variables
FILE *PETSC_STDOUT and FILE *PETSC_STDERR to any file you like, for example /dev/null.  In this way anything PETSc prints will just disappear.
