SMC_ITextStream.EOS (PROP) ¶ PROPERTY EOS : BOOL Returns whether the “End Of Stream” has been reached. Calling Read() if EOS is TRUE will always return 0.

SMC_ITextStream.Name (PROP) ¶ PROPERTY Name : STRING(255) Returns the name of the stream. This could for example be the file name if the stream is file-based.

SMC_ITextStream.Read (METH) ¶ METHOD Read : __XWORD Reads at most nBufSize ASCII characters from the stream into pDst . If an error occurs, 0 is returned, otherwise the number of characters read. Note The number of characters read may be less than nBufSize . InOut: Scope Name Type Comment Return Read __XWORD Input pDst POINTER TO BYTE The destination buffer, needs at least space for nBufSize characters nBufSize __XWORD The size of the destination buffer in bytes

SMC_ITextStream.Reset (METH) ¶ METHOD Reset : BOOL Resets current position of the stream to its beginning InOut: Scope Name Type Return Reset BOOL

SMC_StringStream2 (FB) ¶ FUNCTION_BLOCK SMC_StringStream2 IMPLEMENTS SMC_ITextStream This function block reads strings and presents the contents as a stream of characters to other function blocks such as SMC_ReadNCFromStream . InOut: Scope Name Type Comment Output refillData BOOL Indicates that a reset is requested. The data of the stream must be appended with AppendData from the beginning again. stream SMC_ITextStream Properties: EOS Name Methods: AppendData Close Init SetEndOfData Structure: AppendData (Method) Close (Method) EOS (Property) Init (Method) Name (Property) SetEndOfData (Method)

SMC_Token.SetString (METH) ¶ METHOD SetString : BOOL InOut: Scope Name Type Input pbyString POINTER TO BYTE iSize INT Return SetString BOOL

SMC_TokenQueue.Append (METH) ¶ METHOD Append : BOOL Tries to append a new element to the queue. Returns TRUE if the queue was not full yet, FALSE otherwise. InOut: Scope Name Type Inout Const token SMC_Token Return Append BOOL

SMC_TokenQueue.Capacity (METH) ¶ METHOD Capacity : UDINT The maximum number of samples that can be stored in the queue InOut: Scope Name Type Return Capacity UDINT

SMC_TokenQueue.EndOfData (METH) ¶ METHOD EndOfData : BOOL Returns whether end of data has been reached for the queue InOut: Scope Name Type Return EndOfData BOOL
