fstrm_dump1

Usage

Overview

fstrm_dump opens input-file and prints its framing metadata to stderr and frame data to stdout. The input-file may be "-" to read Frame Streams data from standard input.

Frame data is printed as a single line quoted string with non-printable characters replaced by backslash-prefixed hex escape sequences. For example, a frame containing "Hello, world\n" would have its data printed as:

"Hello, world\x0a"

The only framing metadata expected in a Frame Streams file are the start frame with a content type field, the data frame lengths, and the stop frame. These are printed, respectively, as:

FSTRM_CONTROL_START

FSTRM_CONTROL_FIELD_CONTENT_TYPE (N bytes)

"content-type"

Data frame (N) bytes

FSTRM_CONTROL_STOP

If fstrm_dump is given the second output-file parameter, input frames are additionally written to output-file. This is mainly useful for regression testing of the fstrm_file_writer code.
