	ByRef blob_hash As String
) As Integer

public:
int iGetBlobHash(
	int index, 
	String^% blob_hash
)

public:

	int index, 
	String^% blob_hash
)

member iGetBlobHash : 
        index : int * 
        blob_hash : string byref -> int 


member iGetBlobHash : 
        index : int * 
        blob_hash : string byref -> int

Parameters

index: Type: SystemInt32
zero-based index of the blob hash to retrieve
blob_hash: Type: SystemString
blob content hash hex string

Return Value

Type: Int32
0 on success, 1 if index out of range

Remarks

Returns the blob hash at the specified index. Use iGetBlobHashCount_EVOOBJMETA to determine the valid range of indices. Index 0 typically corresponds to the main data blob, with subsequent indices for auxiliary data (e.g., additional elevation grids or attributes). Returns 0 on success, 1 if the index is out of range.
