#55 decmain.cpp: 2 * possible unterminated strings ?

[dcb]

[decmain.cpp:122]: (error) Dangerous usage of 'infile_name' (strncpy doesn't always null-terminate it).
[decmain.cpp:128]: (error) Dangerous usage of 'outfile_data' (strncpy doesn't always null-terminate it).

Source code is

strncpy(infile_name, iname, sizeof(infile_name));

strncpy(outfile_data, oname, sizeof(outfile_data));

if ((ifp = fopen (infile_name, "rb")) ==NULL)
{
    perror(iname);
    return;
}

if ((fpdata = fopen (outfile_data, "wb")) ==NULL)

Suggest properly terminate the two strings before calling fopen.
