NAME
       pfm_strerror - return constant string describing error code

SYNOPSIS
       #include <perfmon/pfmlib.h>

       const char *pfm_strerror(int code);

DESCRIPTION
       This function returns a string which describes the libpfm error value in code. The string returned by the call is read-only.

       The function must only be used with libpfm calls documented to return specific error codes. The value -1 is not considered a specific error
       code.  Strings and pfm_pmu_t return values cannot be used with this function.  Typically NULL is returned in case of error for string  val-
       ues, and PFM_PMU_NONE is returned for pfm_pmu_t values.

       The function is also not designed to handle OS system call errors, i.e., errno values.

RETURN
       The  function  returns  a  pointer  to  the  constant string describing the error code. The string is in English. If code is invalid then a
       default error message is returned.

ERRORS
       If the error code is invalid, then the function returns a pointer to a string which says "unknown error code".
