SysDirRead

This function of type UDINT can be used to read directory entries.

Each time the function is called, one entry of the directory will be read. As long as “1” is returned, a further entry is in the directory. Thus for reading all entries the function must be called repeatedly until “0” is returned. In this case, the directory is closed and the handle is not valid any more. In every case, the function has to be called until it returns 0 to close the directory.

The information on the particular entries will be written to structure DIRECTORY_INFO.
