sysv equivilant to getwd()

[Thomas J. Pusateri]

I am in need of getting the full pathname of the current working directory.
In SUN OS (BSD) there is a call getwd() that when passed a buffer, returns
that buffer with the current directory. Is there a work around for
SYSTEM V? Is the PWD environment variable standard on all SYSTEM V machines
under bourne shell and korn shell? Could I just do a getenv() on PWD?

Thanks for any info.
