As part of the Performance Co-Pilot Log Import API (see
LOGIMPORT(3)), pmiErrStr translates error codes returned from the
other routines in the Log Import library into printable error
code would normally have a negative value. As a special case, if
code is -1 then the error code returned from the last routine called
in the LOGIMPORT library for this context will be used.
The pmiErrStr_r function does the same, but stores the result in a
user-supplied buffer buf of length buflen, which should have room for
at least PMI_MAXERRMSGLEN bytes.
The set of possible error codes and messages is all those defined by
pmErrStr(3) and PCPIntro(3), plus the additonal ones defined in
<pcp/import.h> with error code names of the form PMI_ERR_....
