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.
