Description:
This function adds a new entry to a
KeyMap, but no value is stored with the entry.
The entry therefore has a special data type represented by symbolic constant
AST__UNDEFTYPE.
An example use is to add entries with undefined values to a KeyMap prior to locking
them with the MapLocked attribute. Such entries can act as placeholders for values
that can be added to the KeyMap later.
Synopsis
void astMapPutU( AstKeyMap
this, const
char key, const
char comment
);
Parameters:
this
Pointer to the KeyMap in which to store the supplied value.
key
A character string to be stored with the value, which can later be used to
identify the value. Trailing spaces are ignored. The supplied string is converted to
upper case before use if the
KeyCase attribute is currently set to zero.
comment
A
pointer to a null-terminated comment string to be stored with the value. A
NULL pointer may be supplied, in which case no comment is stored.
