Read the entire contents of a file to c char *, including new lines

Question

I\'m looking for a cross platform (Windows + Linux) solution to reading the contents of an entire file into a char *.

This is what I\'ve got now:

Answer 1

I've got this:

ssize_t filetomem(const char *filename, uint8_t **result)
{ 
    ssize_t size = 0;
    FILE *f = fopen(filename, "r");
    if (f == NULL) 
    { 
        *result = NULL;
        return -1;
    } 
    fseek(f, 0, SEEK_END);
    size = ftell(f);
    fseek(f, 0, SEEK_SET);
    *result = malloc(size);
    if (size != fread(*result, sizeof(**result), size, f)) 
    { 
        free(*result);
        return -2;
    } 

    fclose(f);
    return size;
}

Meaning of return value:

• Positive or 0: successfully read the file
• minus one: couldn't open file (possibly no such file)
• minus two: fread() failed
