generating header files

help me /prog/

i need to generate a header file which contains an array with content of a number of files and i also need the lenght of these files in an array.

how should i do that?

Read SICP.

OK, why are you wanting to read a bunch of files into an array and put that in a header file?

This is a pretty straightforward affair.  You read the files, record their path from an assigned root folder and their length, then copy that information into arrays in the header file.  If you do this to a fixed collection of files, you will only need to do this once but make sure those files exist whenever the application is run.

If you mean the files may change in number of content, you choose a reading location and have all data in that directory and subdirectory be assumed as valid until proven otherwise by extension or file header.  You read the files each time at runtime and store their information temporarily.

the thing is i dont want to do it at runtime. i want contents of multiple files in one array and their lenght in another one.

As long as the files' contents and the number of files don't change, you should be fine literally writing the contents of them into arrays in the header (hell, if you're going to do that, why not just write all the information in arrays in the header in the first place?).  Just write arrays of strings and an array of whatever type is best for conveying file size.

An alternate approach might be to write this data in binary files and have the header include only the offsets and lengths of each content section so when you want something specific you don't have to search through (multiple) files to get what you want.  Open the known appropriate file, start at position x, and read for y bytes until done, then close.

/* files.h */
char file1[] = "\
#include "file1.txt"
";
int HowLongIsFile1 = sizeof(file1);

wow, that is just what i was looking for.
thank you.

A shame it won't really work, huh?

And for a real answer to you question, write a Perl script.

Wait, you're telling us you had no clue how to get the size of a file?

>>10
i knew that, i just didnt know how to get it into a header/c file.

I'm not surprised that someone who can't even figure out English finds C too challenging.

Hi, Zhivago. I guess we'll be seeing more of you around here.

>>13
I don't know who Zhivago is, but if he understands the value of spelling and grammar, I can only welcome him to /prog/.

man 3 fseek
man 3 ftell

These functions will help you.

>>15
fstat would be rather more useful.

>>16
Yeah, that's fine as long as you don't need your code to work on Windows or whatever.

>>12
I remember hearing zhivago calling to the hal turner show 3 years ago.

>>17
Yeah, that's fine
OMG OPTIMISED
Wondows doesn't use code, silly - only DOTNAT magic!
