NAME

       __pmParseDebug, __pmSetDebugBits - manipulate old-style PCP debugging control bit-fields

C SYNOPSIS

       #include <pcp/pmapi.h>
       #include <pcp/deprecated.h>

       int __pmParseDebug(const char *spec);
       void __pmSetDebugBits(int value);

       cc ... -lpcp

DESCRIPTION

       These  routine  have  been  deprecated and may be removed in a future Performance Co-Pilot (PCP) release.
       Please refer to pmSetDebug(3) and pmClearDebug(3) for replacement functionality.

       __pmParseDebug parses spec assuming it to be a comma separated list of PCP debug flags.

       Each flag may be specified  as  an  integer  or  the  trailing  portion  of  the  symbolic  name  of  the
       corresponding flag as reported by pmdbg(1).  Symbolic names are stripped of the ``DBG_TRACE_'' prefix and
       may appear in either case.

       As a special case, the values ``-1'' and ``ALL'' are treated as synonyms for turning on all  bits  except
       the sign bit in the result, i.e. INT_MAX from <limits.h>.

       For  example  the debug option fetch is defined in the output from pmdbg(3) with the -L option and may be
       specified in spec as 2, FETCH or fetch.

       __pmSetDebugBits may be used to set the bit-fields directly using the encoding in value.  The  effect  is
       additive,  so  consecutive  calls  to  __pmSetDebugBits will set the conjunction of the bits in the value
       arguments.  To clear the bit-fields, see pmClearDebug(3).

DIAGNOSTICS

       If successful, __pmParseDebug returns the value computed by the bit-wise ``or'' of each flag in the spec,
       suitable for assigning to the global debug trace control variable pmDebug.  Otherwise the return value is
       less than 0 to indicate a parsing error.
