My job is to translate a application from C -> C++ that have been installed on a linux distribution.so I wish the functionallity of C and linux.
I have a problem with reading binary file. It says that it reaches the EOF when it encounters a ctrl-Z character before it has reached the actual end of the file.
zcat file.txt.gz | txtToBinary | binaryToOutput
txtToBinary.exe < file.txt | binaryToOutput.exe

The problem is that the program interprets the first ^Z as the end of file.
My solutions has been to do the following when compiling on windows using c++
txtToBinary.exe < file.txt | binaryToOutput.exe
int main(int argc, char* argv []){
int loop (args_t* args){
for (;;){
char data [1024];
int temp = read_msg (data, sizeof (data));
}
int read_msg(void* data, int size){
_setmode(_fileno(stdin), _O_BINARY);
_setmode(0,_0_BINARY);
if(fread(((unsigned char *)data)+sizeof(*hdr),hdr->size-sizeof (*hdr),1,stdin) != 1);
if(feof(stdin))
printf("End of file error\n");
}
I have also tried Cygwin which some of the answers have me. But that also failed.
When looking at answer here in SO, we see Windows, Windows EOF, Binary solution,Binary Mode and Stream data end at byte 26 and Reaching EOF early Windows. They tell me that:
- Windows keys (CTRL + Z, ^Z) makes an end of file
- I have to read in binary format
I found the answer to my question. It had to do with where you read from. You need to put
_setmode(0,_0_BINARY);
in the main() function!!!!!!!! Remember this, otherwise other reads or writes will not be included.
