You should generally use <A HREF="../Sys/CHKMEMQ.html#CHKMEMQ">CHKMEMQ</A> as a short cut for calling this
routine.
<P>
The line, function, file and dir are given by the C preprocessor as
__LINE__, __FUNCT__, __FILE__, and __DIR__

The Fortran calling sequence is simply <A HREF="../Sys/PetscMallocValidate.html#PetscMallocValidate">PetscMallocValidate</A>(ierr)
<P>
No output is generated if there are no problems detected.
