How can I handle files in C across different platforms?

To handle files in C across different platforms, you can use standard file I/O functions like fopen, fread, fwrite, and fclose. These functions are part of the C standard library and are designed to work on various operating systems.

Are there any specific libraries I should consider for better compatibility?

Yes, you might want to consider libraries like Boost.Filesystem or the C++17 filesystem library if you're using C++. For pure C, you can use platform-specific APIs like POSIX for Unix-like systems.

What about handling file paths? They differ between Windows and Unix.

Absolutely! You should use the appropriate path separators: '/' for Unix-like systems and '' for Windows. You can also use functions like realpath() to normalize paths.

Can you give an example of reading a file in a cross-platform way?

Sure! Here's a simple example:

#include <stdio.h>

int main() {
    FILE *file = fopen("example.txt", "r");
    if (file) {
        char buffer[100];
        while (fgets(buffer, sizeof(buffer), file)) {
            printf("%s", buffer);
        }
        fclose(file);
    }
    return 0;
}
