Any one has sample code of Multi-Thread Embbeded SQL in C ?

We want to write multh-thread code using Embbeded SQL in C.

The Open Client version is 15.7 SP100.

The Sybase Document : "Embedded SQL/C Programmers Guide (Open Client) " said it supports Multiple SQLCAs,

but has no sample code about this.

Any one has sample code of Multi-Thread Embbeded SQL in C ?

Thanks!
