const char key,
AstKeyMap that,
int merge )

Pointer to the destination KeyMap.
key
The character string identifying the value to be copied. Trailing spaces are

merge
Indicates what to do if the named entry holds a KeyMap and a KeyMap
entry with the same key already exists in the destination KeyMap. If zero,
the existing destination KeyMap will be deleted and replaced by a copy of the
source KeyMap. If non-zero, all entries in the source KeyMap will be copied
into the existing destination KeyMap using function
astMapCopy.
Notes:
-
This fuction returns without action if the named entry does not exist in the source
KeyMap.
-
Entries from the source KeyMap will replace any existing entries in the destination
KeyMap that have the same key.
-
If the destination entry has a non-zero value for its MapLocked attribute, then an
error will be reported if the source KeyMap contains any keys that do not already exist
within the destination KeyMap.
