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 strerror(3C). The larger, negative error codes are Performance 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.
