NAME
       __pmParseDebug - convert a list of debug flags into an integer


C SYNOPSIS
       #include <pcp/pmapi.h>
       #include <pcp/impl.h>

       int __pmParseDebug(const char *spec);

       cc ... -lpcp


DESCRIPTION
       __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 flag DBG_TRACE_FETCH is defined in /usr/include/pcp/impl.h and may be specified  in
       spec as 2, FETCH or fetch.

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.
