PetscMallocValidate#
Test the memory for corruption. This can be called at any time between PetscInitialize() and PetscFinalize()
Synopsis#
#include "petscsys.h"
PetscErrorCode PetscMallocValidate(int line, const char function[], const char file[])
Input Parameters#
line - line number where call originated.
function - name of function calling
file - file where function is
Return value#
The number of errors detected.
Options Database Keys:.
-malloc_test - turns this feature on when PETSc was not configured with
--with-debugging=0-malloc_debug - turns this feature on anytime
Notes#
Error messages are written to stdout.
This is only run if PetscMallocSetDebug() has been called which is set by -malloc_test (if debugging is turned on) or -malloc_debug (any time)
You should generally use CHKMEMQ as a short cut for calling this routine.
No output is generated if there are no problems detected.
Fortran Note#
The Fortran calling sequence is simply PetscMallocValidate(ierr)
Developers Note#
Uses the flg TRdebugLevel (set as the first argument to PetscMallocSetDebug()) to determine if it should run
