Thread: Copy any type of file to a memory buffer?

Hello, is there any way to copy any type of binary/text file to a memory buffer, and then use the buffer to make a copy of that file?

Code:

char* readFileToBuffer(const char* fname, const char* opts) {
    FILE* fp = fopen(fname, opts);
    if ( !fp ) return 0x00;
    fseek(fp, 0, SEEK_END);
    long fsize = ftell(fp);
    printf("readFileToBuffer(): %d\n", fsize);
    char *buff = (char*)malloc(sizeof(char)* fsize+1);
    fseek(fp, 0, SEEK_SET);
    char* begin = buff;
    fread((char*)buff,  fsize, 1,fp);
    fclose(fp);
    return buff;
}

This, actually can`t be used to copy to a new file from the return buffer.
