The non-reentrant gethostbyXXXX() functions deadlock if called recursively, for
|
|
|
3b9fe0 |
example if libldap needs to be initialized from within gethostbyXXXX() (which
|
|
|
3b9fe0 |
actually happens if nss_ldap is used for hostname resolution and earlier
|
|
|
3b9fe0 |
modules can't resolve the local host name), so use the reentrant versions of
|
|
|
3b9fe0 |
the functions, even if we're not being compiled for use in libldap_r
