SYNOPSISDESCRIPTION
The ensures that a file, part of a crash dump described by crash_cb, is

module files that are a part of the crash dump; see cr_info(3).
pathname is the name of the file to uncompress. Supported compression
methods include gzip(1), which appends a to the filename, and com‐
press(1), which appends Respectively, size and checksum are the
expected size and checksum of the uncompressed file. Either validity
