PMSETDEBUG(3) Library Functions Manual PMSETDEBUG(3)
pmSetDebug, pmClearDebug - manipulate PCP debugging control options
#include <pcp/pmapi.h>
int pmSetDebug(const char *spec);
int pmClearDebug(const char *spec);
cc ... -lpcp
Within the libraries and applications of the Performance Co-Pilot
(PCP) there is an extensive set of debugging options that may be
enabled or disabled at run-time.
Both pmSetDebug and pmClearDebug parse spec assuming it to be a comma
separated list of PCP debug option names.
The names of the available options may be found using the -l argument
to pmdbg(1).
As a special case, the name ``all'' is treated as a synonym for
identifying all option names.
pmSetDebug will set the corresponding options, while pmClearDebug
will clear the corresponding options.
Consecutive calls to either routine will be additive. For example
the following code fragments are equivalent in terms of the final
configuration of the debug options.
sts = pmClearDebug("all");
sts = pmSetDebug("appl0");
sts = pmSetDebug("pdu,fetch");
sts = pmSetDebug("fetch,profile,context");
sts = pmClearDebug("appl0");
sts = pmClearDebug("all");
sts = pmSetDebug("pdu,fetch,profile,context");
An earlier implementation of the PCP debug facilities used a bit-
vector and for backwards compatibility the elements of spec may
include decimal values corresponding to those bit-values. Refer to
pmdbg(1) for more details of this deprecated format.
pmdbg(1)
If successful, these routines return 0, otherwise the return is
PM_ERR_CONV to indicate a parsing error.
