The '''PUT #''' TCP/IP statement sends unformatted(raw) data to an open connection using a user's handle.
|
|
|
|
|
|
{{PageSyntax}}
|
|
:: PUT #handle, , data
|
|
|
|
|
|
*Sends data (this could be a string, variable array, user defined type, etc) to a connection handle returned by the [[_OPENCLIENT]], [[_OPENHOST]] or [[_OPENCONNECTION]] '''QB64''' functions.
|
|
|
|
|
|
:::::'''Communicating using unformatted/raw streamed data:'''
|
|
* Benefit: Communicate with any TCP/IP compatible protocol (eg. FTP, HTTP, web-pages, etc)
|
|
* Disadvantage: Streamed data has no 'message length' as such, just a continuous bunch of bytes all in a row. Some messages get fragmented and parts of messages can (and often do) arrive at different times.
|
|
* The position parameter(between the commas) is not used in TCP/IP statements.
|
|
:::::'''Your program MUST cater for these situations manually.'''

''Example: ''
|
|
|
|
{{CodeStart}}
|
|
'''PUT #'''c, , a$ 'sends data (this could be a string, variable array, user defined type, etc)
|
|
{{Cl|GET (TCP/IP statement)|GET}} #o, , b$ 'reads any available data into variable length string b$
|
|
'''GET #'''o, , x%
|
|
{{CodeEnd}}
|
|
|
|
|
|
''Explanation:'' b$'s length is adjusted to the number of bytes read. Checking [[EOF]](o) is unnecessary. If 2 bytes are available, they are read into x%, if not then nothing is read and [[EOF]](o) will return -1
