This function returns number of entries and descriptive string buffer size for a specified entity. This function can be called before an inquiry routine in order to determine the sizes of the output arrays and descriptive strings.
Examples
In this example, we determine the number of dimension mapping entries.
nmaps = EOS_SW_NENTRIES(swathID, 2)
Syntax
Result = EOS_SW_NENTRIES( swathID, entrycode [, LENGTH=variable] )
Return Value
Number of entries or FAIL (–1) in the case of an improper swath id or entry code.
Arguments
swathID
Swath id (long) returned by EOS_SW_CREATE or EOS_SW_ATTACH.
entrycode
Entrycode (long). Allowable values are:
- 0 = Dimensions
- 1 = Dimension Mappings
- 2 = Indexed Dimension Mappings
- 3 = Geolocation Fields
- 4 = Data Fields
Keywords
