PETSc version 3.15.5
SNESLineSearchMonitorSet
Sets an ADDITIONAL function that is to be used at every iteration of the nonlinear solver to display the iteration's progress. 
Synopsis
#include "petscsnes.h" 
PetscErrorCode  SNESLineSearchMonitorSet(SNESLineSearch ls,PetscErrorCode (*f)(SNESLineSearch,void*),void *mctx,PetscErrorCode (*monitordestroy)(void**))
Logically Collective on SNESLineSearch
Input Parameters
|  | ls | - the SNESLineSearch context | 
|  | f | - the monitor function | 
|  | mctx | - [optional] user-defined context for private data for the
monitor routine (use NULL if no context is desired) | 
|  | monitordestroy | - [optional] routine that frees monitor context
(may be NULL) | 
Notes
Several different monitoring routines may be set by calling
SNESLineSearchMonitorSet() multiple times; all will be called in the
order in which they were set.
Fortran Notes
Only a single monitor function can be set for each SNESLineSearch object
