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.
