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
