Function 53h Handle Name Functions
EMS handles may be named. Each name may be any eight characters.
At installation, all handles have their name initialized to ASCII
nulls (binary zeros). There is no restriction on the characters
which may be used in the handle name (ASCII chars 00h through
0FFh). A name of eight nulls (zeroes) is special, and indicates a
handle has no name. Nulls have no special significance, and they
can appear in the middle of a name. The handle name is 64 bits of
binary information to the EMM. Functions 53h and 54h provide a
way of setting and reading the names associated with a particular
handle. Function 53h manipulates names by number. When a handle
is assigned a name, at least one character in the name must be a
non-null character in order to distinguish it from a handle
without a name. |
