CRLF is a Mailutils filter which converts line separators from LF (ASCII 10) to CRLF (ASCII 13 10) and vice-versa.
In decode mode, translates each CRLF sequence to LF. Takes no arguments.
In encode mode, replaces each LF character with the CRLF sequence. If created with the -n option, the filter produces a "normalized" output, by preserving input CRLF untouched (by default they are translated to CR CR LF).
The following object, declared in the header mailutils/filter.h, describes this filter:
extern mu_filter_record_t mu_crlf_filter;
The example below shows how to create a CRLF filter instance in decode mode for reading:
int rc; /* Return code */
mu_stream_t flt; /* Filter stream */
mu_stream_t input; /* Input stream */
initialize_input_stream (&stream);
rc = mu_filter_create (&flt, input, "CRLF", MU_FILTER_DECODE, MU_STREAM_READ);
This filter is also available under the name RFC822, which is deprecated.
