NAME

6       autresizeblock - resizes a memory block
7

SYNOPSIS

9       #include "aut101.h"
10         char ∗autresize( Source, OldSize, NewSize )
11          char         ∗Source;
12          unsigned int OldSize;
13          unsigned int NewSize;
14

PARAMETERS

16       Source              Pointer to the memory block to be resized.
17
18       OldSize             Old size of the memory block.
19
20       NewSize             New size of the memory block.
21

DESCRIPTION

23       autresizeblock resizes a memory block  from OldSize to NewSize. if New‐
24       Size is greater than OldSize then the new bytes are set to zero.
25

RETURN VALUE

27       autresizeblock returns the pointer to the resized block.
28

ERRORS

30       "autresize: resize error, can't continue !"

38               char ∗ s;
39            {
40               t = (char ∗)autresizeblock( t, strlen(t)+1, strlen(t)+strlen(s)+1);
41               strcat(t, s);
42               return t;
