Description
Erases the data value associated with an ini file entry.
Call DeleteKey to erase a data value associated with an ini file entry. Section is string containing the name of an ini file section, and Ident is a string containing the name of the key for which to set a nil (Delphi) or NULL (C++) value.
Note: Attempting to erase a data value in a nonexistent section or attempting to erase data from a nonexistent key are not errors. In these cases, DeleteKey creates the section and key and sets its initial value to an empty value.
