Mixing C/C++ with LE-conforming IBM HLASM

[Larry Slaten]

I am attempting to use the C/C++ FOPEN function to open a SYSLIB DD 
pointing to a concatenation of executable libraries.  Then extract the 
DCB address so that I can use it to populate the LOAD and BLDL macro.  
This would make it easier to keep the root program RENT.  I realize that 
I can code the DCB in the root assembler program and do what is 
necessary to keep the program RENT.  But, using the C/C++ functions 
would make it simpler.  I have used the FOPEN function to open the data 
set, retrieved the file pointer.  The file pointer points to another 
31-bit address. I have dumped the storage around that 31-bit address, it 
still doesn't look like a DCB.  I  do see "SYSLIB" at +84 bytes, so I 
appear to be close to the answer.  Does anybody know to obtain the DCB 
address using the file pointer returned by FOPEN?
