Hi Pavel,

Each individual 40-character string in the array is supposed to have a 
terminating 0 byte, although CA may transport all 40 bytes.  Clients should be 
prepared to handle values that fill all 40 characters and should terminate the 
string after the 40th character if necessary.  Since we use calloc() to 
allocate the buffer all elements should start out empty.

Is that what you were asking?
