-write_sec

Introduction

The -write_sec option writes the current grib message section (0-8) to file. The only options that applies to the file are the -header, -no_header, -append, and -no_append options. The default -header option put a 4-byte unsigned integer header and trailer around the section data. The header and trailer are the number of bytes of the section.

The -write_sec option is by codes that need low-level access to the grib data.

Usage

-write_sec N file            N = 0..8
                             file = file to write
