sqlegdsc API - Start a database connection services (DCS) directory scan

Stores a copy in memory of the Database Connection Services directory entries, and returns the number of entries. This is a snapshot of the directory at the time the directory is opened.

The copy is not updated if the directory itself changes after a call to this API. Use sqlegdgt API and sqlegdcl API to release the resources associated with calling this API.

API and data structure syntax

SQL_API_RC SQL_API_FN
  sqlegdsc (
        short * pNumEntries,
        struct sqlca * pSqlca);

SQL_API_RC SQL_API_FN
  sqlggdsc (
        struct sqlca * pSqlca,
        short * pNumEntries);

sqlegdsc API parameters

pNumEntries: Output. Address of a 2-byte area to which the number of directory entries is returned.
pSqlca: Output. A pointer to the sqlca structure.

Usage notes

The caller of the scan uses the returned value pNumEntries to allocate enough memory to receive the entries. If a scan call is received while a copy is already held, the previous copy is released, and a new copy is collected.
