That is a nice enhancement for the C language under z/OS. As a general
rule, I _try_ to avoid any functions which start with one or two
underscores. These are generally "reserved" for the implementer and so may
not be available on a different compiler. The __jobname() is a nice example
of a reasonable extension for z/OS, or z/VSE. Another nice one might be
__userid() to return the RACF id under which the process is running.
Hi John,
Yes - identifiers that begin with double-underscore are reserved
for the C implementation; that's why our implementation uses
those (to avoid conflicts.)
Along with __jobname(), we have:
__stepname()
__procname()
__get_cpuid()
__userid()
which can make it very handy indeed. The Dignus C library
manual has more details.
