I'm trying to include sqlhdr.h so that the compiler will tell me if I do something stupid like call rdefmtdate() with the wrong variable types, but it doesn't seem to pick up the prototype. If I explicitly put the function prototype for rdefmtdate() into my code I do get a compiler warning. If I simply do a #include "sqlhdr.h" I get nothing. I do see the #ifdef __STDC__ and I've made sure this is defined. What am I missing? Platform is AIX 5.2 ESQL version is 7.24.UC5 (we're retro here)

Thanks for the reply. I had tried that too. I did figure it out though. Our compiler was using extended C by default and silently ignores defining of __STDC__. Adding the command line option "-qlanglvl=extc89" (or stdc89 or stdc99 or saa or saal2) got me my prototypes. Setting INFORMIXC=xlc also works.
