# PetscInfoDestroy

Destroys and resets internal `PetscInfo()` data structures.

## Synopsis

    #include "petscsys.h"
    PetscErrorCode PetscInfoDestroy(void)

Not Collective

## Notes

This is automatically called in `PetscFinalize()`. Useful for changing filters mid-program, or culling subsequent `PetscInfo()` calls down the line.

Users calling this routine midway through a program should note that `PetscInfoDestroy()` constitutes a full reset of `PetscInfo()`. It flushes, then closes, the current info file, re-enables all classes, and resets all internal state. Finally – and perhaps crucially – it disables `PetscInfo()` as-if-by `PetscInfoAllow(PETSC_FALSE)`.
