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.
