NAME
       kmsg_dump_get_buffer - copy kmsg log lines

SYNOPSIS
       bool kmsg_dump_get_buffer(struct kmsg_dumper * dumper, bool syslog, char * buf,
                                 size_t size, size_t * len);

ARGUMENTS
       dumper
           registered kmsg dumper

       syslog
           include the “<4>” prefixes

       buf
           buffer to copy the line to

       size
           maximum size of the buffer

       len
           length of line placed into buffer

DESCRIPTION
       Start at the end of the kmsg buffer and fill the provided buffer with as many of the the
       *youngest* kmsg records that fit into it. If the buffer is large enough, all available
       kmsg records will be copied with a single call.

       Consecutive calls will fill the buffer with the next block of available older records, not
       including the earlier retrieved ones.

       A return value of FALSE indicates that there are no more records to read.
