NOTES ************************************************************** *** *** *** This file is SOSD. Porters must change the data types *** *** appropriately on their platform. See notes/pcport.doc *** *** for more information. *** *** *** ************************************************************** If the symbol SQLCA_STORAGE_CLASS is defined, then the SQLCA will be defined to have this storage class. For example: #define SQLCA_STORAGE_CLASS extern will define the SQLCA as an extern. If the symbol SQLCA_INIT is defined, then the SQLCA will be statically initialized. Although this is not necessary in order to use the SQLCA, it is a good pgming practice not to have unitialized variables. However, some C compilers/OS's don't allow automatic variables to be init'd in this manner. Therefore, if you are INCLUDE'ing the SQLCA in a place where it would be an automatic AND your C compiler/OS doesn't allow this style of initialization, then SQLCA_INIT should be left undefined -- all others can define SQLCA_INIT if they wish. If the symbol SQLCA_NONE is defined, then the SQLCA variable will not be defined at all. The symbol SQLCA_NONE should not be defined in source modules that have embedded SQL. However, source modules that have no embedded SQL, but need to manipulate a sqlca struct passed in as a parameter, can set the SQLCA_NONE symbol to avoid creation of an extraneous sqlca variable. MODIFIED lvbcheng 07/31/98 - long to int jbasu 12/12/94 - Bug 217878: note this is an SOSD file losborne 08/11/92 - No sqlca var if SQLCA_NONE macro set Clare 12/06/84 - Ch SQLCA to not be an extern.
