-error_final¶

Introduction¶

The -error_final tests the final value and can raise an error condition when wgrib2 returns. For version 1, the only value that can be tested is the count of the number time the option is called in the grib-processing phase.

When -error_final is intialized, the count is set to zero. Then -error_final increments the count whenever it processes a grib message. Finally when -error_final is run after processing all the grib messages, it tests count to a specified integer and sets the error return.

Usage¶

-error_final count TEST INTEGER
   TEST = eq, ne, lt, gt, le, ge
   INTEGER integer
   sets return error to one if "count TEST INTEGER" is true
