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.
