LONG GpiQueryMetaFileLength(hmf)
HMF hmf;    /* metafile handle */
 
The GpiQueryMetaFileLength function returns the total length, in bytes, of
the metafile specified by hmf. The function is typically used to determine
the number of bytes of data to retrieve using the GpiQueryMetaFileBits
function.
 
Parameter  Description

hmf        Identifies the metafile.
 
Return Value
 
The return value is the metafile length if the function is successful or
GPI_ALTERROR if an error occurred.
