NINT srctyp, pVOID dest, NINT destlen);

Description of use |
seghnd |
Handle returned by PutXtdKeySegmentDef() or GetXtdKeySegmentDef(). |
src |
Pointer to data used to construct segment. |
srclen |
Size in bytes of the region pointed by src. However, srclen is ignored unless kseg_ssiz was set to ctKSEG_SSIZ_PROVIDED. |
srctyp |
srctyp should be set to one of the c-tree Plus field types (e.g., CT_STRING or CT_UNICODE). However, srctyp is ignored unless kseg_styp was set to ctKSEG_STYP_PROVIDED. |
