API Parameters

pSqlca
Output. A pointer to the sqlca structure. For more information about this structure, see SQLCA.

pNumTablespaces
Output. The total number of table spaces in the connected database.

pppTablespaceData
Output. The caller supplies the API with the address of a pointer. The space for the table space query data is allocated by the API, and a pointer to that space is returned to the caller. On return from the call, the pointer points to an array of SQLB_TBSPQRY_DATA pointers to the complete set of table space query data.

reserved1
Input. Always SQLB_RESERVED1.

reserved2
Input. Always SQLB_RESERVED2.

Usage Notes

This API uses the lower level services, namely:

to get all of the table space query data at once.

If sufficient memory is available, this function returns the number of table spaces, and a pointer to the memory location of the table space query data. It is the user's responsibility to free this memory with a call to sqlefmem (see sqlefmem - Free Memory).

If sufficient memory is not available, this function simply returns the number of table spaces, and no memory is allocated. If this should happen, use sqlbotsq - Open Tablespace Query, sqlbftpq - Fetch Tablespace Query, and sqlbctsq - Close Tablespace Query, to fetch less than the whole list at once.
