ExAll

Examine an entire directory

Declaration

Source position: amigados.pas line 1628

Arguments

Function result

An indicator of if ExAll() is done. If False is returned, either ExAll() has completed in which case IoErr() is ERROR_NO_MORE_ENTRIES or an error occurred. If a True is returned ExAll() must be called again until it returns False.

Description

Lock must be on a directory. Size is the size of the buffer supplied. The buffer will be filled with (partial) ExAllData structures, as specified by the type field.

ed_Type is a value from those shown below that determines which information is to be stored in the buffer. Each higher value adds a new thing to the list as described in the table below:

ED_NAME

FileName

ED_TYPE

Type

ED_SIZE

Size in bytes

ED_PROTECTION

Protection bits

ED_DATE

3 longwords of date

ED_COMMENT

Comment (will be nil if no comment)

ED_OWNER

Owner user-id and Group-id

Thus, ED_OWNER gives only filenames, and ED_OWNER gives everything.

The ed_Next entry gives a pointer to the next entry in the buffer. The last entry will have nil in ed_Next.

This is an incremental list meaning that if you specify ED_OWNER you will get all attributes!

Filesystems that support ExAll() must support at least up to ED_COMMENT. If a filesystem doesn't support a particular type, ERROR_BAD_NUMBER must be returned.

ed_Next

Pointer to the next entry in the buffer. The last entry has a nil value for ed_Next.

The control structure have the following fields.

eac_Entries

the number of entries in the buffer after a call to ExAll(). Make sure that your code handles the case when eac_Entries is 0 and ExAll() returns True.

eac_LastKey

Must be initialized to 0 before calling ExAll() for the first time.

eac_MatchString

If nil then information on all files will be returned. If non-nil it's interpreted as a pointer to a string used for pattern matching which files to return information on. This string must have been parsed by ParsePatternNoCase()!

ac_MatchFunc

to a hook that will be called to decide if an entry should be included in the buffer. If nil, no matching function will be called. The hook is called as follows
