/prog/ - save binary data to file

Name: Anonymous 2007-09-17 1:06 ID:RgM63GYu

How do I do this C, C++?

I want to save a lot of ints, and I know that they only take up 32Bits (i think) but I'm using a string like " 2105601606 1065160 5610651" to store these goddam fuckers

he;lp?

learn C.. this kind of thing is trivial once you know the language

sorry C and C++ lives in silicon valley, they are travelling round the world at the moment, come by later

fopen and fputs i think are the only functions you need to know, and fclose. C doesn't distinguish between binary and text files, though i haven't learnt about binary files, i assume they're the same

Read the fread(3) and fwrite(3) man pages. Write some code. Learn about endianness. Cry. Read the htonl(3) and ntohl(3) man pages.

Use uint32_t from stdint.h.

Not supported by many implementations.
but yes, use (u)intN_t for fixed length objects.

Use UNITIИU for fixed length objects.
