HP-UX 11i v3.0 critical impact:

gai_strerror, getnameinfo - behaviour differences (CrCh397)

NW Impacts

Problem description

On HPUX 11iv3, gai_strerror and getnameinfo have been enhanced and the behaviour have been changed.

These APIs are defined under _XOPEN_SOURCE_EXTENDED macro on HPUX 11iv3 as,

const char *gai_strerror(int encode);

int getnameinfo(const struct sockaddr *sa, socklen_t salen, char *host, socklen_t hostlen, char *serv, socklen_t servlen, int flags);

Where as, on Tru64, their definitions are as follows.

char *gai_strerror(int ecode);

int getnameinfo(const struct sockaddr *sa, socklen_t salen, char *node, size_t *nodelen, char *serv, size_t servlen, int flags);

The return value of the gai_strerror API has changed from "char *" to "const char *".

A new non-zero error code, EAI_OVERFLOW, is introduced in the getnameinfo API. It returns an EAI_OVERFLOW error if an argument buffer overflow occurs.

The type of the "hostlen" and "servlen" variables in getnameinfo is changed from size_t to socklen_t.
