Ascii and binary
Author
Hi!
I have here a littel problem. If i open an acsii file (*.txt) in binary mode via fopen and read the whole file in a buffer and write it back in binary mode then the output file is in binary. How can i avoid this? Which files must be open in ascii mode?
Thanks, Christian

You should show the code. Or atleast tell what functions you are using.

Ok... here is my code:
FILE* s1;
unsigned int Size1;
char* buffer1;
// try to open 2 source files
if ((s1 = fopen("In.txt", "rb")) != 0)
{
// obtain file size.
fseek (s1 , 0 , SEEK_END);
Size1 = ftell (s1);
rewind (s1);
buffer1 = (char*) malloc (Size1);
fread (buffer1, 1, Size1, s1);
fclose(s1);
}
if ((s1 = fopen("Out.txt", "wt")) != 0)
{
fwrite(&buffer1, 1, Size1, s1);
fclose(s1);
}

Just write it back as binary, and it''ll write back the exact same thing. Mixing binary and ascii isn''t wise.

I have found the mistake!
fwrite(&buffer1, 1, Size1, s1);
should be
fwrite(buffer1, 1, Size1, s1);
fwrite(&buffer1, 1, Size1, s1);
should be
fwrite(buffer1, 1, Size1, s1);
