#define INCL_DOSMEMMGR
 
USHORT DosGetSeg(sel)
SEL sel;    /* selector of shared-memory segment */
 
The DosGetSeg function obtains access to the shared-memory segment
identified by the specified segment selector. Although a process can receive
the selector for a shared-memory segment from another process, the process
must first use the DosGetSeg function to access the segment.
 
Parameter  Description
────────────────────────────────────────────────────────────────────────────
 
sel        Specifies the selector for the shared-memory segment.
 
Return Value
 
The return value is zero if the function is successful. Otherwise, it is an
error value.
 
Comments
 
DosGetSeg obtains access only to shared-memory segments created by using the
DosAllocSeg function with the fAttrs parameter set to SEG_GETTABLE.
 
DosGetSeg can be issued from ring 2, but the shared-memory segment must be a
ring 3 segment.
