C include files, system service declarations?

» close window

The Question is:

 
I'm trying to use the sys$set_devicew call in a C program, but I get the error
 that says it's "implicitely declared as a function".  Apparently, it's in an
 #include file that I don't have included in my program, but I can't locate any
 include file that do
es have sys$set_devicew in it.  Can you tell me what I need to #include to be
 able to use sys$set_devicew?
 
 

The Answer is :

 
  Examples of common OpenVMS header files in C include the following:
 
    starlet.h
    lib$routines.h
    str$routines.h
    smg$routines.h
 
  In the case of C, look in starlet.h for the system service (sys$)
  declarations.
 
  If requested during the C compiler installation, searchable copies
  of the C headers are loaded into SYS$SYSROOT:[DECC$LIB...]*.H
 
  You should follow the reinstallation or the system symbol extraction
  documentation that is provided by the various compilers after an
  OpenVMS upgrade -- this to extract the latest system definitions.
  In the specific case of the C compiler, the documented procedure for
  extracting the latest OpenVMS system declarations is the upgrade of
  or the reinstallation of a C compiler kit.
