    File I/O Read and Check

    Hi, I need help with reading and checking from a binary file. I want to read until a i reach a certin byte. Heres an example...

    File:

    ...291....09...../...0927.. [ect]

    EOF

    I want to read till the '/' and leave the pointer at that position.

    Can anyone help me?

    Thanks, ~rab

    use fgetc() in a loop -- it returns only 1 character at a time, then just check each byte read.

    actually, since this is c++ board, not C, you should use fstream's get() method.

    Perhaps these might serve as an alternative:

    Code:
    istream& get (char* s, streamsize n, char delim );
    Reads up to the delim in your case '/', but doesn't read it, rather leaves the pointer on it for the next read.
    -------------------------------------------------------------------------------------
    or

    Code:
    istream& getline (char* s, streamsize n, char delim );
    Reads file up until the delim in your case '/'. The delim is extracted and discarded.
