Description:
The slog2_dump_logs_to_file() writes a snapshot of slog2 logs to a file, using the same log line format as slog2info.
Returns:
0 on success, or -1 if an error occurred (errno is set).
Errors:
- EACCES
- The slog2 parsing library couldn't be opened.
- EINVAL
- The file argument is NULL.
Examples:
Write only the logs from the current process:
FILE *file = fopen( "mylogs", "w" );

fclose( file );

FILE *file = fopen( "mylogs", "w" );
slog2_dump_logs_to_file( file, SLOG2_DUMP_LOGS_ALL );
fclose( file );
