SysDirRead (FUN) ¶ FUNCTION SysDirRead : RTS_IEC_RESULT Read next directory entry. Writes the entry in pszDirEntry. InOut: Scope Name Type Comment Return SysDirRead RTS_IEC_RESULT Returns the runtime system error code (see CmpErrors.library) ERR_OK: Entry could be read ERR_END_OF_OBJECT: If end of directory list was reached ERR_PARAMETER: If one of the parameters is invalid ERR_BUFFERSIZE: If iMaxDirEntry is too short to get the complete directory entry string Note Typically after error ERR_BUFFERSIZE , the dir-handle is set to the next entry, so this entry will be missed! Input hDir RTS_IEC_HANDLE Handle to directory opened with SysDirOpen Inout szDirEntry STRING OUT_PARAMETER: Directory entry as string Input diMaxDirEntry DINT OUT_PARAMETER: Max number of bytes to write in pszDirEntry pDirInfo POINTER TO DirInfo OUT_PARAMETER: Directory information NOTE: Can be 0 (so only directory name is provided in pszDirEntry)
