NAME

       mbkrealloc - mbk memory reallocator

SYNOPSYS

       #include "mut.h"
       void ∗mbkrealloc(pt, bytes)
       void ∗pt;
       unsigned int bytes;

PARAMETERS

       pt                  Pointer to an already allocated area, allocated using mbkallocP

       bytes               Number of memory bytes to be contiguously allocated

DESCRIPTION

       mbkrealloc  returns  a  block of bytes length, for any purpose.  It increases or decreases
       the size of the area, and return a pointer to the new block.  It is  now  a  day  only  an
       encapsulation of the system realloc function, but may evolve to a special allocator in the
       future. Its use is strongly encouraged.

       Remark :            a  global  variable,  long  mbkrealloc_stat,  updates  the  number  of
                           allocated  bytes,  and  may be accessed by anyone to see the amount of
                           allocated memory.

RETURN VALUE

       mbkrealloc returns a pointer to a bytes long block.

ERROR

       "∗∗∗ mbk error ∗∗∗ mbkrealloc impossible : not enough memory"
              System break can't be moved anymore, no more  memory  can  be  retrieved  from  the
              system.

EXAMPLE

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