-check_pdt_size¶

Introduction¶

Wgrib2 v3.0.1 will check the size of the Product Definition Template (PDT, Section 4). If the PDT is wrong size, wgrib2 will exit with a delayed fatal error. The fatal error is delayed so the user can investigate the contents of the bad grib message. Note that it is possible to seg fault because Section 4 is a different size than expected, and the rest of the grib message may be corrupted.

You may skip the pdt size check using the option -check_pdt_size 0. You would use this option if wgrib2 calculates the incorrect size of Section 4.

Usage¶

-check_pdt_size    0 disable PDT size check
                   1 enable  PDT size check

Example¶

$ wgrib2 png.grb2 -check\_pdt\_size 0
1:4:YY=2009
