NAME
pfm_set_options - set performance monitoring library debug options
SYNOPSIS
#include <perfmon/pfmlib.h>
int pfm_set_options(pfmlib_options_t *opt);
DESCRIPTION
This function can be called at any time to adjust the level of debug of
the library. You can adjust the verbosity or the debug level. In both
cases, extra output will be generated on the standard output when the
library gets called. This can be useful to figure out how the PMC
registers are initialized.
The opt argument is a pointer to a pfmlib_options_t structure which is
defined as follows:
typedef struct {
unsigned int pfm_debug:1;
unsigned int pfm_verbose:1;
} pfmlib_options_t;
Setting pfm_debug to 1 will enable debug messages whereas setting
pfm_verbose will enable verbose messages.
RETURN
The function returns whether or not it was successful.A return value of
PFMLIB_SUCCESS indicates success, otherwise the value is the error
code.
ERRORS
PFMLIB_ERR_INVAL
the argument is invalid, most likely a NULL pointer.
