overførsel af binær fil

I andet argument af fopen kan du angive, at du vil åbne file som en binær fil:

fopen(filename, \"rb\");

Jeg har dog erfaring med, at fopen, fread, etc. foretager en eller anden form for konvertering, så jeg brugte _open, _read og _write. Desuden skulle jeg sætte mode\'en for standard output:

_setmode(1, _O_BINARY);

se evt. her:

Jeg gør sådan her.(laver selv samme projekt)
ændringer er:
open(\"filnavn\",ios::binary);
close(\"filnavn\",ios::binary);

tak for svarene.
Jeg/vi har vist selv fundet en løsning... Arbejder med gruppearbejde, så det er egentlig ikke mig som kigger på det der, men vender snart tilbage.

til jbh: fopen(filename, \"rb\");
der er da ikke noget flag som hedder \"rb\" ???

jo, jo - to minutters søgning på nettet:

2.12.3.7 fopen
Declaration:

FILE *fopen(const char *filename, const char *mode);
Opens the filename pointed to by filename. The mode argument may be one of the following constant strings: r read text mode
w write text mode (truncates file to zero length or creates new file)
a  append text mode for writing (opens or creates file and sets file pointer to the end-of-file)
rb read binary mode
wb  write binary mode (truncates file to zero length or creates new file)
ab  append binary mode for writing (opens or creates file and sets file pointer to the end-of-file)
r+ read and write text mode
w+ read and write text mode (truncates file to zero length or creates new file)
a+  read and write text mode (opens or creates file and sets file pointer to the end-of-file)
r+b or rb+ read and write binary mode
w+b or wb+ read and write binary mode (truncates file to zero length or creates new file)
a+b or ab+ read and write binary mode (opens or creates file and sets file pointer to the end-of-file)


If the file does not exist and it is opened with read mode (r), then the open fails.

If the file is opened with append mode (a), then all write operations occur at the end of the file regardless of the current file position.

If the file is opened in the update mode (+), then output cannot be directly followed by input and input cannot be directly followed by output without an intervening fseek, fsetpos, rewind, or fflush.

On success a pointer to the file stream is returned. On failure a null pointer is returned.

som tidligere nævnt fandt jeg selv en løsning. Men pga. den lange svartid deler jeg hermed pointsne ud.

Hvilken løsning kom du frem til???
