\fBParameters\fP
.RS 4
\fIlevel\fP one of the constants shown in the table below and defined in the \fBpapi\&.h\fP header file\&.
.br
The possible debug levels for debugging are shown below\&.
.PD 0
.IP "\(bu" 1

\fBReturn values\fP
.RS 4
\fIPAPI_OK\fP
.br
\fIPAPI_EINVAL\fP The debug level is invalid\&.
.br
.br
The current debug level is used by both the internal error and debug message handler subroutines\&.
.br
The debug handler is only used if the library was compiled with -DDEBUG\&.
.br
The debug handler is called when there is an error upon a call to the PAPI API\&.
.br
The error handler is always active and its behavior cannot be modified except for whether or not it prints anything\&.
.RE
.PP
The default PAPI debug handler prints out messages in the following form:
.br
PAPI Error: Error Code code, symbol, description
.PP
If the error was caused from a system call and the return code is PAPI_ESYS, the message will have a colon space and the error string as reported by strerror() appended to the end\&.
.PP
The PAPI error handler prints out messages in the following form:
.br
PAPI Error: message\&.
