NAME

       pmErrStr, pmErrStr_r - convert a PMAPI error code into a string

C SYNOPSIS

       #include <pcp/pmapi.h>

       const char *pmErrStr(int code);
       char *pmErrStr_r(int code, char *buf, int buflen);

       cc ... -lpcp

DESCRIPTION

       Translate  an  error  code  into  a  text string, suitable for generating a diagnostic message.	The pmErrStr_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 PM_MAXERRMSGLEN bytes.

       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 strerror(3C).  The larger, negative error codes are Performance Metrics Application Program-
       ming Interface (PMAPI) error conditions and pmErrStr(3) returns an appropriate PMAPI error string, as determined by code.

NOTES

       pmErrStr returns a pointer to a static buffer, so the returned value is only valid until the next call to pmErrStr and hence is not thread-
       safe.  Multi-threaded applications should use pmErrStr_r instead.

NAME

       pmerr - translate Performance Co-Pilot error codes into error messages

SYNOPSIS

       pmerr code ...
       pmerr -l

DESCRIPTION

       pmerr accepts standard Performance Co-Pilot (PCP) error codes via the code argument(s) and generates the corresponding error text.

       Each code may be an integer, a hexadecimal value or a hexadecimal value prefixed by either ``0x'' or ``0X''.

       Error codes must be less than zero, so if code is a positive number, a warning message is produced, and the negated value is used.

       The alternative use of the -l option causes all known error codes to be listed, along with their symbolic names and error text.

PCP ENVIRONMENT

       Environment  variables  with  the prefix PCP_ are used to parameterize the file and directory names used by PCP.  On each installation, the
       file /etc/pcp.conf contains the local values for these variables.  The $PCP_CONF variable may be used to specify an alternative	configura-
       tion file, as described in pcp.conf(5).
