# PetscOptionsTail

Ends a section of options begun with PetscOptionsHead() See, for example, KSPSetFromOptions_GMRES(). Collective on the communicator passed in PetscOptionsBegin()

### 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
