Имя (Name)

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

Синопсис C (C Synopsis)

#include <pcp/pmapi.h>

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

cc ... -lpcp


Описание (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(3). 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.


Примечание (Note)

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.
