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
Output Effect#
Error messages are written to stdout.
Notes#
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.
The Fortran calling sequence is simply PetscMallocValidate(ierr)
No output is generated if there are no problems detected.
Developers Note#
Uses the flg TRdebugLevel (set as the first argument to PetscMallocSetDebug()
) to determine if it should run
