techPurgeTechFile

techPurgeTechFile( 
d_techID 
) 
=> t / nil

Description

Deletes the database from virtual memory if the close count for the file is 0. Internally, the system maintains a count of the number of times you open and close a specific technology database. The count increments when you open and decrements when you close. When the close count is 0 and the system needs more virtual memory, it automatically purges the technology database to free the memory. This function lets you manually purge the technology database.

Arguments

d_techID

The identifier of the technology database.

Value Returned

t	The memory was purged.
nil	The technology database does not exist or the close count is greater than 0.

Example

techPurgeTechFile(tfID)
=> t

Frees the memory allocated to the technology database identified by tfID.
