fread and char *

Im trying to read in a file to a char * with fread, but after it is done there is junk at the end, how can i fix this.

Here is an excert from my class

Code:

---

void mikestring::readfile(char * filename)
{

FILE* f = fopen(filename,"rb");

fseek (f , 0 , SEEK_END);
long fileSize = ftell (f);
rewind (f);

        delete[] mystring;                //Clear Old Memmory

        MyLen = fileSize;
    MyCap = MyLen+1;
   
        mystring = new char[fileSize];
        fread (mystring,1,fileSize,f);

fclose(f);

}

Your code looks okay. Since you are doing a binary read -
IF the file was originally written as a text file, there will be an ascii 26 character that marks the end of the text file. fread ignores this EOF mark and reads beyond it - the junk you see.

Try getting rid of junk like this:

Code:

---

  char *start=mystring;
  char *buf= strchr(mystring,26);
  if(buf!=NULL)
        while(  ((int)buf - (int)start ) >=filesize) *buf++=0x00;

Don't do this to a binary-created file, you will clobber good data.
