NAME
__pmParseDebug - convert a list of debug flags into an
integer
C SYNOPSIS
#include <pcp/impl.h>
int __pmParseDebug(const char *spec)
cc ... -lpcp
DESCRIPTION
__pmParseDebug parses spec assuming it to be a comma sepa
rated 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.
