Gets information about the specified annotation file and fills the specified ANNFILEINFO structure with the information.
#include "ltwrappr.h"
virtual L_INT LAnnContainer::FileInfo(pszFile, pAnnFileInfo, uStructSize)
Character string containing the name of the annotation input file.
Pointer to the ANNFILEINFO structure to be filled. For more information, refer to the ANNFILEINFO structure.
Size in bytes, of the structure pointed to by pAnnFileInfo, for versioning. Use sizeof(ANNFILEINFO).
