Strings are limited to 255 characters. Here is a set of functions and function blocks for working with not limited text buffers. Text buffers are dynamically allocated or re-allocated.

The application is responsible for freeing all allocated text buffers. However, all allocated buffers are automatically released when the application stops.

Memory management/Miscellaneous

TxbManager: Main gatherer of text buffer data in memory.

TxbLastError: Get detailed error report about last call.

Allocation/exchange with files

TxbNew: Allocate a new empty buffer.

TxbNewString: Allocate a new buffer initialized with string.

TxbFree: Release a text buffer.

TxbReadFile: Allocate a new buffer from file.

TxbWriteFile: Store a text buffer to file.

Data exchange

TxbGetLength: Get length of a text buffer.

TxbGetData: Store text contents to an array of characters.

TxbGetString: Store text contents to a string.

TxbSetData: Store an array of characters to a text buffer.

TxbSetString: Store string to text buffer.

TxbClear: Empty a text buffer.

TxbCopy: Copy a text buffer.

Sequential reading

TxbRewind: Rewind sequential reading.

TxbGetLine: Sequential read line by line.

Sequential writing

TxbAppend: Append variable value.

TxbAppendLine: Append a text line.

TxbAppendEol: Append end of line characters.

TxbAppendTxb: Append contents of another buffer.

TCP socket information - Text buffer

TxbRcvTCP: Store characters received from a TCP socket

TxbSendTCP: Sends characters of a text buffer to a valid TCP socket
