GRIB2_INIT_AND_ASSIGN

#define GRIB2_INIT_AND_ASSIGN

(

ret

)

Value:

        do { \
        NC_Dispatch *_d = NC_GRIB2_initialize(); \
        (ret) = (_d != NULL) ? NC_NOERR : NC_ENOTNC; \
    } while(0)

GRIB2_INIT_OK

#define GRIB2_INIT_OK

(

)

(NC_GRIB2_initialize() != NULL)

GRIB2_MAGIC_LEN

#define GRIB2_MAGIC_LEN   4

GRIB2 magic number length (4 bytes: "GRIB")

NC_FORMATX_NC_GRIB2

#define NC_FORMATX_NC_GRIB2   NC_FORMATX_UDF0

GRIB2 format uses UDF2 slot for dispatch table model field (see nep.h for slot allocation)

NC_GRIB2_ABBREV_LEN

#define NC_GRIB2_ABBREV_LEN   64

Maximum length of a g2c parameter abbreviation string

NC_MAX_GRIB2_MESSAGES

#define NC_MAX_GRIB2_MESSAGES   4096

Maximum number of GRIB2 messages supported per file

Typedef Documentation

NC_GRIB2_FILE_INFO_T

typedef struct NC_GRIB2_FILE_INFO NC_GRIB2_FILE_INFO_T

Per-file GRIB2 state

NC_GRIB2_PROD_INFO_T

typedef struct NC_GRIB2_PROD_INFO NC_GRIB2_PROD_INFO_T

NC_VAR_GRIB2_INFO_T

typedef struct NC_VAR_GRIB2_INFO NC_VAR_GRIB2_INFO_T

Per-variable format-specific information (used as NC_VAR_INFO_T.format_var_info)
