filters

Show all headers | View raw

Hi,

it´s probably a FAQ, though I haven´t found any good info on it: How do
you go about writing a filter, i. e. a program that reads data from
stdin and processes it?

Since indefinte amounts of data could be read from stdin, they can´t
just be put into some (ever increasing) buffer. Using a buffer of
limited size can make it difficult to process the data because the
buffer could be too small.

What´s the solution for this?
