(
c-addr u fam --
fileid ior )
Create the file named in the character string specified by
c-addr and
u, and open it with file access method
fam. The meaning of values of
fam is
implementation defined. If a file with the same name already
exists, recreate it as an empty file.
If the file was successfully created and opened,
ior is
zero,
fileid is its identifier, and the file has been
positioned to the start of the file.
Otherwise,
ior is the implementation-defined I/O result
code and
fileid is undefined.
