Hi,

I am writing a C program that issues IFI READA calls
and want to pass an ECB to it (that I have defined as
int in my C program), that gets posted by DB2 when the buffer
gets filled.

Is there a simple way to wait for an ECB to get posted in
a C program? I use IBM C/C++ (we do not have SAS/C installed).
I think they have a WAIT1(&ecb) in ostask.h. I want to accomplish
something similar, or is my only chance to write an external 
assembler program that calls wait?

What would my signal/interrupt situation then be in case my C
program receives a signal?

I appreciate any help or pointers,
Peter

Sure is:

selectex()

Peter -

  selectex() might be something to look it.

  It's available in the IBM C and Dignus C runtime libraries.
 
  selectex() lets you wait on an ECB (or a time-out, or a socket.)

  I believe SAS has something similar called select_ecb().
