\fBndb_drop_table\fR
drops the specified
NDB
table\&. (If you try to use this on a table created with a storage engine other than
NDB, the attempt fails with the error
723: No such table exists\&.) This operation is extremely fast; in some cases, it can be an order of magnitude faster than using a MySQL
DROP TABLE
statement on an
NDB
table\&.

.sp 1
Specify a list of directories to search for a CA file\&. On Unix platforms, the directory names are separated by colons (:); on Windows systems, the semicolon character (;) is used as the separator\&. A directory reference may be relative or absolute; it may contain one or more environment variables, each denoted by a prefixed dollar sign ($), and expanded prior to use\&.
.sp
Searching begins with the leftmost named directory and proceeds from left to right until a file is found\&. An empty string denotes an empty search path, which causes all searches to fail\&. A string consisting of a single dot (\&.) indicates that the search path limited to the current working directory\&.
.sp
If no search path is supplied, the compiled\-in default value is used\&. This value depends on the platform used: On Windows, this is
\endb\-tls; on other platforms (including Linux), it is
$HOME/ndb\-tls\&. This can be overridden by compiling NDB Cluster using
\fB\-DWITH_NDB_TLS_SEARCH_PATH\fR\&.
