int bdelky(BTA* btact, char* key);
The bdelky function deletes a key from
the current root in the file associated with the
btact context pointer. The key, a
character string, is passed via the pointer in
key. If the key does not exist,
bdelky returns the error code
QNOKEY. bdelky
returns zero on successful deletion of a key.
If bdelky is called with a
key value of NULL, the delete operation
will act against the current key, as selected by
bfndky, bnxtky or
bprvky operations. This capability is
designed to allow deletion of a duplicate key, presumably
based on other, application managed, attributes.
A non-zero return from bdelky indicates
an error occurred during the key deletion process.
