sqleAttachToCtx API parameters

pCtx: Input. A valid context previously allocated by sqleBeginCtx.
reserved: Reserved for future use. Must be set to NULL.
pSqlca: Output. A pointer to the sqlca structure.

Usage notes

If more than one thread is attached to a given context, only one of the attached threads can issue SQL at a given time, since they share the same connection and unit of work. In this case, when one thread is executing SQL, the other threads will wait for that SQL to complete before they are allowed to execute SQL.
