critical impact:

sockatmark - not supported; temporarily available (CrUn174)

Problem description

The sockatmark function exists on Tru64 UNIX, but not on HP-UX. This function is available on a temporary basis in the Tru64 UNIX Migration Environment for HP-UX.

The sockatmark function enables applications to determine which received data precedes the out-of-band data and which data follows the out-of-band data.

The Migration Environment contains Tru64 UNIX Application Programming Interfaces (APIs), development tools, and commands and utilities to assist customers in migrating their applications from Tru64 UNIX to HP-UX.

Identifiers

sockatmark

Old behavior

Solution description

The sockatmark function is in the Tru64 UNIX Migration Environment for HP-UX.

Applications will be able to use this function from the Tru64 UNIX Migration Environment for HP-UX. Please note that the Migration Environment is temporary.

For a long-term solution, recode your application and replace the sockatmark function with an ioctl call with the SIOCATMARK request parameter.

New behavior

ioctl(s, SIOCATMARK, (char *)&atmark);
