I'm not sure whether file attributes and permissions should be considered to be part of the I/O infrastructure of a language. -- Shmuel (Seymour J.)

Does ANSI stream I/O provide full control of such as O_CREAT, O_EXCL, O_TRUNC, O_APPEND, ... as syscall does? -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
