<h3><font color=#C00040>DESQview 2.50+ - SEND MESSAGE - READINTO - GET NEXT MAIL MESSAGE</font></h3>
<PRE>
AH = 12h
BH = 13h
BL = mailbox from which to read
00h DWORD on top of stack is mailbox handle
02h use given task's mailbox (task's handle on top of stack)
03h use current task's default mailbox.
<p><b>STACK:</b><br>DWORD size of buffer in bytes
DWORD pointer to buffer<br>
<p><b>Return:</b><br>STACK: DWORD number of bytes read
</PRE>
<p><b>Program:</b>
DESQview 2.5x is distributed as part of DESQview/X 1.0x
<p><b>Notes:</b>
This call blocks if no input is available, but will return less than
the requested number of bytes if some (but insufficient) data is
available.
Use this call instead of AH=12h/BH=04h if the mailbox has flag bits
4 or 5 set, as common memory may be exhausted by that call when
attempting to read the next message
