CNVNewFolder

int CNVNewFolder (const char *parentPath, const char *folderName);

Purpose

Creates a new folder in the network variable path you specify.

If you specify a folderName that already exists, CNVNewFolder returns an error.

Note Note  This library may return CNVDisconnectedError if you browse folders created after creating the network variable browser. If you need to create folders and browse them, National Instruments recommends that you create the browser after you create the folders.

Parameters

Input
Name Type Description
parentPath const char * The parent's machine-relative path. You can specify a process name or a process name followed by one or more folder names delimited with the backslash path separator. Do not include a trailing backslash in the path.

Note Note  National Instruments recommends that you use only alphanumeric characters in process, folder, and variable names. If the name contains single quotation mark ('), backslash (\), period (.), newline (\n), or carriage return (\r) characters, you must escape these characters by enclosing the name in single quotation marks. If the contains single quotation mark characters, you also must precede that character with another single quotation mark.

For example, to specify process'Name\folder.Name as a path, enter the following:

  • 'process''Name' as the process name
  • 'folder.Name' as the folder name

Thus, the value you specify for parentPath is 'process''Name\'folder.Name'.

folderName const char * The name of the network variable folder.

Note Note  National Instruments recommends using only alphanumeric characters in folder names.

Return Value

Name Type Description
status int Return value indicating whether the function was successful. One indicates that a next item was found, zero indicates that a next item was not found, and a negative number indicates that an error occurred.

You can call CNVGetErrorDescription to obtain a string that describes the error.
