Aggregates as many buffers as possible from bl in a new buffer of maximum length max_len .

sep is written after each copied buffer (also after the last one). All the aggregated buffers are removed from the list and replaced by the new one, followed by any additional (non-aggregated) data. Nothing happens if max_len is not enough to aggregate at least 2 buffers.

Parameters

max_lenthe maximum length of the aggregated buffer
septhe separator to put between buffers during aggregation

exclusiveCharacter classes to be replaced even if they are also in inclusive.
replaceThe character to replace the specified character classes with.
Returns
True if the string was not modified, false otherwise.
