** SOURCE FILE NAME: utilapi.c
**
** SAMPLE: Checks for and prints to the screen SQL warnings and errors
**
** This utility file is compiled and linked in as an object module
** with non-embedded SQL sample programs by the supplied makefile
** and build files.
**
** DB2 APIs USED:
** sqlaintp -- Get Error Message
** sqlogstt -- Get SQLSTATE Message
** sqleatin -- Attach to an Instance
** sqledtin -- Detach from an Instance
**
** Included functions:
** SqlInfoPrint - prints to the screen SQL warnings and errors
** CmdLineArgsCheck1 - checks the command line arguments, version 1
** CmdLineArgsCheck2 - checks the command line arguments, version 2
** CmdLineArgsCheck3 - checks the command line arguments, version 3
** CmdLineArgsCheck4 - checks the command line arguments, version 4
** InstanceAttach - attach to instance
** InstanceDetach - detach from instance
