GetLTVRecord

Read the variable-length record with a key less than target.

Short Name

LTVREC()

Type

ISAM function

Declaration

COUNT GetLTVRecord(COUNT keyno, pVOID target, pVOID recptr, pVRLEN plen)

Description

GetLTVRecord() is the same as its fixed-length counterpart, GetLTRecord(), except one argument has been added: plen acts as both an input and output parameter. On input, *plen contains the length of the output buffer. On output, *plen contains the actual data record length. If the length of the output buffer is less than the actual record length, a partial read is performed.

Read the GetLTRecord() function description for additional important information.
