| + | ======Synopsis:====== | ||
| + | $[[frewind]](<file descriptor>) | ||
| + | |||
| + | ======Technical:====== | ||
| + | This function resets the file pointer back to the beginning of the file. | ||
| + | The next [[read]] or [[readb]] in the file after this call will read the | ||
| + | first line of the file. | ||
| + | |||
| + | This function returns the [[ferror]] value, which is zero if the operation | ||
| + | succeeds and is non-zero if an error occurs. | ||
| + | |||
| + | The //file descriptor// must have been a value previously returned by | ||
| + | the [[open]] function. | ||
| + | |||
| + | ======Returns:====== | ||
| + | <file> | ||
| + | -1 Error: //file descriptor// was not previously returned by [[open]] | ||
| + | 0 The file pointer was reset to the beginning | ||
| + | 1 The file pointer could not be reset. | ||
| + | </file> | ||
