Hello,

I'm writing some library routines that will live in .h files and want to be able to obtain the name of the CSECT that their code will be residing in -- at compile time.

For example, I'm pretty sure I could do something like this:

#define theCsect "MYCSECT"
...
printf("theCsect detected an issue...");
​

which should resolve to:

printf("MYCSECT detected an issue...");​

And then make sure that theCsect is always  #defined in every module.

In assembler there is the built in variable &SYSSECT, which is set to the CSECT name specified in the assembly.  In Metal C, I can

#pragma map(main,MYCSECT)​

​​​So what I'm looking for is some sort of compile time function/built-in/system variable/system macro/whatever that could be used in lieu of the #define technique above, perhaps similar to the __function__ macro (which will return the name of the current function being compiled, not the enclosing CSECT.

Thanks,
Scott​

Hi Scott,

Unfortunately, we do not know of a way to do this. You can use the #pragma csect directive to name your csect, but that is a "set" operation, not a "get" operation.

Others following this topic group please feel free to chime in.

Subject: XL C (Metal) - At compile time is there a system built-in, macro, or function that can be used to obtain the CSECT?
