NAME

       pmErrStr - convert a PMAPI error code into a string


C SYNOPSIS

       #include <pcp/pmapi.h>

       const char *pmErrStr(int code)

       cc ... -lpcp


DESCRIPTION

       Translate  an  error code into a text string, suitable for
       generating a diagnostic message.  By convention, all error
       codes  are  negative.   The small values are assumed to be
       negated versions of the Unix error  codes  as  defined  in
       <errno.h>  and  the  strings  returned  are  as  per  str­
       error(3C).  The larger, negative error codes  are  Perfor­
       mance  Metrics  Application  Programming Interface (PMAPI)
       error conditions and pmErrStr(3)  returns  an  appropriate
       PMAPI error string, as determined by code.

       The string value is held in a single static buffer, so the
       returned value is  only  valid  until  the  next  call  to
       pmErrStr.
