fwrite malloc
However, if i then want to read from the file to get this data back, I believe I need to read in the structure, read the nameLength variable, malloc ..., Just remove & in fread and fwrite . That's because outdata already points to location, allocated by malloc() . P.S. Don't forget to free(outdata);.
