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  pmDe-
       bug.  Otherwise the return value is less than 0 to indicate a parsing error.
