NAME

       autresizeblock - resizes a memory block

SYNOPSYS

       #include "aut101.h"
         char ∗autresize( Source, OldSize, NewSize )
          char         ∗Source;
          unsigned int OldSize;
          unsigned int NewSize;

PARAMETERS

       Source              Pointer to the memory block to be resized.

       OldSize             Old size of the memory block.

       NewSize             New size of the memory block.

DESCRIPTION

       autresizeblock resizes a memory block  from OldSize to NewSize. if NewSize is greater than
       OldSize then the new bytes are set to zero.

RETURN VALUE

       autresizeblock returns the pointer to the resized block.

ERRORS

       "autresize: resize error, can't continue !"
              System break can't be moved anymore, no more  memory  can  be  retrieved  from  the
              system.

EXAMPLE

       #include "aut101.h"
            char ∗concatstring( t, s )
               char ∗ t;
               char ∗ s;
            {
               t = (char ∗)autresizeblock( t, strlen(t)+1, strlen(t)+strlen(s)+1);
               strcat(t, s);
               return t;
            }
