EOS_PT_LEVELINFO

EOS_PT_LEVELINFO

This function returns information about the fields in a given level. Typical reasons for failure are an improper point id or level number.

Examples


In this example, we return information about the Desc-Loc (1st) level defined previously:

nflds = EOS_PT_LEVELINFO(pointID2, 0, fldlist, fldtype, fldorder)

The last variable is useful only when information on an entire point is requested.

Syntax


Result = EOS_PT_LEVELINFO(pointID, level, fieldlist, fldtype, fldorder)

Return Value


Returns number of fields if successful and FAIL (–1) otherwise.

Arguments


pointID

Point id (long) returned by EOS_PT_CREATE or EOS_PT_ATTACH.

level

Point level (0-based long).

fieldlist

A named variable that will contain field names (string) in level.

fldtype

A named variable that will contain the number HDF data type (long) of each field.

fldorder

A named variable that will contain the order (long) of each field.
