I think you need to check the return value from asprintf, not
displayfd_string:
When successful, these functions return the number of bytes printed,
just like sprintf(3). If memory allocation wasn't possible, or some
other error occurs, these functions will return -1, and the contents of
strp are undefined.
Cheers,
