+.TH PMPARSEDEBUG 3 "PCP" "Performance Co-Pilot"
+.SH NAME
+\f3__pmParseDebug\f1 \- convert a list of debug flags into an integer
+.SH "C SYNOPSIS"
+.ft 3
+#include <pcp/pmapi.h>
+.br
+#include <pcp/impl.h>
+.sp
+int __pmParseDebug(const char *\fIspec\fP);

+.SH DESCRIPTION
+.B __pmParseDebug
+parses
+.I spec
+assuming it to be a comma separated list of PCP debug flags.
+.PP
+Each flag may be specified as an integer or the
+trailing portion of the symbolic name of the corresponding flag as reported
+by
+.BR pmdbg (1).
+Symbolic names are stripped of the ``DBG_TRACE_'' prefix and may appear
+in either case.
+.PP
+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. \c
+.B INT_MAX
+from
+.IR <limits.h> .
+.PP
+For example the debug flag
+.B DBG_TRACE_FETCH
+is defined in
+.I /usr/include/pcp/impl.h
+and may be specified in
+.I spec
+as
+.BR 2 ,
+.B FETCH
+or
+.BR fetch .
+.SH SEE ALSO
+.BR pmdbg (1)
+.SH DIAGNOSTICS
+If successful,
+.B __pmParseDebug
+returns the value computed by the bit-wise ``or'' of each flag in the
+.IR spec ,
+suitable for assigning to the global debug trace control variable
+.BR pmDebug .
+Otherwise the return value is less than 0 to indicate a parsing error.
