astMapType
-
Get the data type of an entry in a KeyMap
- Description:
- This function returns a value indicating the data type of a
named entry in a KeyMap. This is the data type which was used when the
entry was added to the KeyMap.
- Synopsis:
- int astMapType( AstKeyMap
this, const char
key )
- Parameters:
-
this
-
Pointer to the KeyMap.
-
key
-
The character string identifying the KeyMap entry. Trailing
spaces are ignored.
The supplied string is converted to upper case before use if the
KeyCase attribute is currently set to zero.
- Returned Value:
-
astMapType()
-
One of AST__INTTYPE (for integer), AST__SINTTYPE (for
short int),
AST__BYTETYPE (for unsigned bytes
- i.e. unsigned chars
) AST__DOUBLETYPE (for double
precision floating point), AST__FLOATTYPE (for single
precision floating point), AST__STRINGTYPE (for character string),
AST__OBJECTTYPE (for AST Object pointer), AST__POINTERTYPE (for
arbitrary C pointer) or AST__UNDEFTYPE (for undefined values
created by
astMapPutU).
AST__BADTYPE is returned if the supplied key is not found in the KeyMap.
- Notes:
- A function value of AST__BADTYPE will be returned if an error has
already occurred, or if this function should fail for any reason.
