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:.

-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
