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 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.
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".
