# FindClose

Dispose resources allocated by a FindFirst/FindNext sequence.

## Declaration

Source position: dosh.inc line 106

`procedure FindClose(`
`var f: SearchRec`
`);`

## Description

FindClose frees any resources associated with the search record F.

This call is needed to free any internal resources allocated by the FindFirst or FindNext calls.

The Unix implementation of the Dos unit therefore keeps a table of open directories, and when the table is full, closes one of the directories, and reopens another. This system is adequate but slow if you use a lot of searchrecs.

So, to speed up the findfirst/findnext system, the FindClose call was implemented. When you don't need a searchrec any more, you can tell this to the Dos unit by issuing a FindClose call. The directory which is kept open for this searchrec is then closed, and the table slot freed.

Remark: | It is recommended to use the Linux call Glob when looking for files on Linux.

## Errors

Errors are reported in DosError.
