## NAME

**pmiSetHostname** - set the source host name for a LOGIMPORT archive

## C SYNOPSIS

## DESCRIPTION

As part of the Performance Co-Pilot Log Import API (see [**LOGIMPORT**(3)](/LOGIMPORT/3.md)), **pmiSetHostname** sets the source hostname in the current context to be *value*.

In the absence of a call to **pmiSetHostname** the source hostname defaults to the hostname of the localhost.

## DIAGNOSTICS

**pmiSetHostname** returns zero on success else a negative value that can be turned into an error message by calling [**pmiErrStr**(3)](/pmiErrStr/3.md).
