Re: [Iverilog-devel] Problems reading .wav file with $fgets

[Martin W. <ic...@ma...>]

fgetc() is the standard 'C' method for reading a byte at a time from a 
binary file, so it's reasonable to use $fgetc for the same purpose. You 
indicate that it's a binary file when you open the file.

The attached test program demonstrates that the 'C' fgets() function 
doesn't skip null characters.
