Описание (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).
Диагностика (Diagnostic)
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.
