Come devo fare per capire quali sono i modi validi per l’apertura di un
file?
Se lancio ri Kernel#open mi dice: “See the table of valid modes on page
331”
Si ma … come ci si va alla pagina 331?
Grazie.
Ciao Mauro, fai “ri IO” e ti darà le info sui vari modes. In ogni caso
cercalo su IO piuttosto che Kernel.
ti riassumo qui cosa dice il mio ri
Mode | Meaning
-----±-------------------------------------------------------
“r” | Read-only, starts at beginning of file (default mode).
-----±-------------------------------------------------------
“r+” | Read-write, starts at beginning of file.
-----±-------------------------------------------------------
“w” | Write-only, truncates existing file
| to zero length or creates a new file for writing.
-----±-------------------------------------------------------
“w+” | Read-write, truncates existing file to zero length
| or creates a new file for reading and writing.
-----±-------------------------------------------------------
“a” | Write-only, starts at end of file if file exists,
| otherwise creates a new file for writing.
-----±-------------------------------------------------------
“a+” | Read-write, starts at end of file if file exists,
| otherwise creates a new file for reading and
| writing.
