Assembler Equivalent
os9 I$DELETE
Description
Unlink deletes the directory entry whose name is pointed to by
"fname". If the entry was the last link to the file, the file
itself is deleted and the disc space occupied made available
for re-use. If, however the file is open, in any active task,
the deletion of the actual file is delayed until the file is
closed.
Diagnostics
Zero is returned from a successful call, -1 if the file does
not exist, if its directory is write-protected, or cannot be
searched, if the file is a non-empty directory or a device.
