directory path identifies the directory whose contents you want to determine.
If this is not an existing directory, this function sets file names and directory names to empty arrays and returns an error.
|
 |
pattern restricts the files and directories returned to those whose names match pattern.
The pattern matching in this function is similar to the matching used in matching wildcards in Windows and UNIX filenames and is not like the regular expression matching performed by the Match Pattern function. If you specify characters other than the question mark character (?) or the asterisk character (*), the function displays only files or directories that contain those characters. You can use the question mark character (?) to match any single character. You can use the asterisk character (*) to match any sequence of one or more characters.
If pattern is an empty string, the VI returns all files and directories.

 |
datalog type can be any data type and restricts the file names returned to only datalog files containing records of the specified data type.
Datalog records contain a timestamp cluster and a cluster of the front panel data.

 |
error in describes error conditions that occur before this VI or function runs.
The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurs before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.
 |
status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE.
|
 |
code is the error or warning code. The default is 0.
If status is TRUE, code is a non-zero error code. If status is FALSE, code is 0 or a warning code.
|
 |
source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.
|
|
 |
dup directory path returns directory path unedited.
|
 |
file names contains the names of the files found in the specified directory.
|
 |
directory names contains the names of the directories found in the specified directory.
If directory path is an empty path, directory names contains the names of the drives on the computer.
|
 |
error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces.
Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.
 |
status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.
|
 |
code is the error or warning code.
If status is TRUE, code is a non-zero error code. If status is FALSE, code is 0 or a warning code.

source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning.
