PetscOptionsTail
Ends a section of options begun with PetscOptionsHead() See, for example, KSPSetFromOptions_GMRES(). Collective on the comm used in PetscOptionsBegin() or obj used in PetscObjectOptionsBegin()
Synopsis
#include <petscoptions.h>
PetscErrorCode PetscOptionsTail(void)
Notes
Must be between a PetscOptionsBegin()/PetscObjectOptionsBegin() and a PetscOptionsEnd()
Must be preceded by a call to PetscOptionsHead() in the same function.
This needs to be used only if the code below PetscOptionsTail() can be run ONLY once.
See, for example, PCSetFromOptions_Composite(). This is a return(0) in it for early exit
from the function.
This is only for use with the PETSc options GUI
