I have added the code for usehunk==5 :) Note the comment ;)
<snip>
byte *COM_Load (char *path, into use)
{
FILE *he;
byte *buff;
char base[32];
into Len;
buf = NULL; // quiet compiler warning
// look for it in the filesystem or pack files
len = com_filesize = COM_FOpenFile (path, &h);
if (!h)
return NULL;
// extract the filename base name for hunk tag
COM_FileBase (path, base);
if (usehunk == 1)
buf = Hunk_AllocName (len+1, base);
else if (usehunk == 2)
buf = Hunk_TempAlloc (len+1);
else if (usehunk == 0)
buf = Z_Malloc (len+1);
else if (usehunk == 3)
buf = Cache_Alloc (loadcache, len+1, base);
else if (usehunk == 4)
{
if (len+1 > loadsize)
buf = Hunk_TempAlloc (len+1);
else
buf = loadbuf;
}
else if (usehunk == 5)
{
buf = (byte *)Mem_Malloc(len + 1); // YWB: FIXME, this is evil.
}
else
Sys_Error ("COM_LoadFile: bad usehunk");
if (!buf)
Sys_Error ("COM_LoadFile: not enough space for %s", path);
((byte *)buf)[len] = 0;
#ifndef SERVERONLY
Draw_BeginDisc ();
#endif
fread (buf, 1, len, h);
fclose (h);
#ifndef SERVERONLY
Draw_EndDisc ();
#endif
return buf;
}
...Half-Life adds a new hunk (usehunk==5) which I'll let the Valve guys
describe more fully (if they respond) ;)
The "hunks" are basically just different memory management techniques.
