.SH SYNOPSIS
.B pmerr
.I code
\&...
.br
.B pmerr
\f3\-l\f1
.SH DESCRIPTION
.B pmerr
accepts
standard Performance Co-Pilot (PCP)
error codes via the
.I code
argument(s) and generates the corresponding error text.
.PP
Each
.I code
may be an integer, a hexadecimal value or a hexadecimal value prefixed
by either ``0x'' or ``0X''.
.PP
Error codes must be less than zero, so if
.I code
is a positive number, a warning message is produced, and the
negated value is used.
.PP
The alternative use of the
.B \-l
option causes all known error codes to be listed, along with their
symbolic names and error text.
.SH "PCP ENVIRONMENT"
Environment variables with the prefix
.B PCP_
are used to parameterize the file and directory names
used by PCP.
On each installation, the file
.I /etc/pcp.conf
contains the local values for these variables.
The
.B $PCP_CONF
variable may be used to specify an alternative
configuration file,
as described in
.BR pcp.conf (5).
