Why do ask next eldest children, that is, if I file inside only one character, I don't write operation, read out is a character, but
To write again after reading the words will be read out is 4095

CodePudding user response:

Should be 4 k, you write to characters' z ', the current cursor backwards one, give you fill behind the 4 k - 1 empty placeholder characters,
If in front with a while loop call: fseek (stream, 0, SEEK_SET); Pointer to reset, the count is 4 k,

Feel this is the place where c standard library very sick, or directly use the open read write good, simple, direct, brutal,,,
