File Rename Function on Microware OS-9

Question

Is there a system call (C API function, not assembler) to rename a file in Microware OS-9 3.03?

If not, is there an accepted way to accomplish this task?

Answer 1

To answer the second part: I worked around this by doing an open on the file. If the open succeeded then I infer the file exists. If the open failed then I check the error in errno. If it's EOS_PNNF, then I infer the file does not exist. Anything else is an error.

I would still like to know about the first part of the question.
