Test the memory for corruption. This can be called at any time between PetscInitialize() and PetscFinalize()


#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

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


You should generally use CHKMEMQ as a short cut for calling this routine.

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)

No output is generated if there are no problems detected.

Fortran Notes#

The Fortran calling sequence is simply PetscMallocValidate(ierr)
