NAME

       open_trunc - open a file for writing

SYNTAX

       #include <open.h>

       int open_trunc(const char *filename);

DESCRIPTION

       open_trunc opens the file filename for write-only use and returns the file handle.  If the
       file exists, it will be truncated to zero bytes length.  If it does not exist, it will  be
       created  with  mode  0644.  If there was an error opening or creating the file, open_trunc
       returns -1 and sets errno accordingly.
