pfm_strerror - return constant string describing error code
#include <perfmon/pfmlib.h>
const char *pfm_strerror(int code);
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
values, 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.
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.
If the error code is invalid, then the function returns a pointer to
a string which says "unknown error code".
