◆ vpCDEBUG

#define vpCDEBUG ( level )

Value:

  if (VP_DEBUG_MODE < level)                                                                                           \
    ;                                                                                                                  \
  else                                                                                                                 \
    std::cout << "(L" << level << ") " << __FILE__ << ": " << __FUNCTION__ << "(#" << __LINE__ << ") : "

vpCDEBUG(level) work like the C++ output stream std::cout.

#define VP_DEBUG        // Activate the debug mode
#define VP_DEBUG_MODE 2 // Activate debug level 1 and 2
 
#include <visp3/core/vpDebug.h>
 
#ifdef ENABLE_VISP_NAMESPACE
using namespace VISP_NAMESPACE_NAME;
#endif
 
int main()
{
  // C++-like debug printings
  vpCTRACE << "C++-like trace" << std::endl; // stdout
  vpCERROR << "C++-like error trace" << std::endl; // stderr
 
  // Printing if VP_DEBUG defined and VP_DEBUG_MODE value >= 2
  vpCDEBUG(2) << "C++-like debug trace level 2" << std::endl; // stdout
}

◆ vpDEBUG_ENABLE

#define vpDEBUG_ENABLE ( level )

Value:

(VP_DEBUG_MODE >= level)

vpDEBUG_ENABLE(level) is equal to 1 if the debug level level is greater than the debug mode VP_DEBUG_MODE, 0 else.

#define VP_DEBUG        // Activate the debug mode
#define VP_DEBUG_MODE 2 // Activate debug level 1 and 2
 
#include <visp3/core/vpDebug.h>
 
#ifdef ENABLE_VISP_NAMESPACE
using namespace VISP_NAMESPACE_NAME;
#endif
 
int main()
{
  // Check the active debug levels
  std::cout << "Debug level 1 active: " << vpDEBUG_ENABLE(1) << std::endl;
  std::cout << "Debug level 2 active: " << vpDEBUG_ENABLE(2) << std::endl;
  std::cout << "Debug level 3 active: " << vpDEBUG_ENABLE(3) << std::endl;
}

◆ vpDEBUG_TRACE

#define vpDEBUG_TRACE (vpTraceOutput(__FILE__, __LINE__, __FUNCTION__, false))

vpDEBUG_TRACE works like printf, but prints only if the tracing level level is greater than the debug level VP_DEBUG_MODE.

#define VP_DEBUG        // Activate the debug mode
#define VP_DEBUG_MODE 2 // Activate debug level 1 and 2
 
#include <visp3/core/vpDebug.h>
 
#ifdef ENABLE_VISP_NAMESPACE
using namespace VISP_NAMESPACE_NAME;
#endif
 
int main()
{
  // Printing if VP_DEBUG defined and VP_DEBUG_MODE value >= 2
  vpDEBUG_TRACE(2, "C-like debug trace level 2");  // stdout
  vpDERROR_TRACE(2, "C-like error trace level 2"); // stderr
}

See also: vpDERROR_TRACE()

Definition at line 526 of file vpDebug.h.

◆ vpDERROR_TRACE

#define vpDERROR_TRACE (vpTraceOutput(__FILE__, __LINE__, __FUNCTION__, true))

vpDERROR_TRACE works like printf, but prints only if the tracing level is smaller than the debug level VP_DEBUG_MODE.

#define VP_DEBUG        // Activate the debug mode
#define VP_DEBUG_MODE 2 // Activate debug level 1 and 2
 
#include <visp3/core/vpDebug.h>
 
#ifdef ENABLE_VISP_NAMESPACE
using namespace VISP_NAMESPACE_NAME;
#endif
 
int main()
{
  // Printing if VP_DEBUG defined and VP_DEBUG_MODE value >= 2
  vpDEBUG_TRACE(2, "C-like debug trace level 2");  // stdout
  vpDERROR_TRACE(2, "C-like error trace level 2"); // stderr
}

◆ vpERROR_TRACE

#define vpERROR_TRACE (vpTraceOutput(__FILE__, __LINE__, __FUNCTION__, true))

Used to display error messages on the error stream. Prints the name of the file, the function name and the line where it was used. Use like this : vpERROR_TRACE("my error message number %d", i); with any "printf" string.

#define VP_TRACE // To activate trace mode
#define VP_DEBUG_MODE 2 // Activate debug level 1 and 2
 
#include <visp3/core/vpDebug.h>
 
#ifdef ENABLE_VISP_NAMESPACE
using namespace VISP_NAMESPACE_NAME;
#endif
 
int main()
{
  // Printing depend only VP_DEBUG_MODE value is >= 1
  vpTRACE(1, "C-like trace level 1");              // stdout
  vpERROR_TRACE(1, "C-like error trace level 1");  // stderr

◆ vpIN_FCT

#define vpIN_FCT (vpTraceOutput(__FILE__, __LINE__, __FUNCTION__, false, "begin "))

Works like vpTRACE() and should be used at the beginning of a function.

#define VP_TRACE // To activate the trace mode
#include <visp3/core/vpDebug.h>
 
#ifdef ENABLE_VISP_NAMESPACE
using namespace VISP_NAMESPACE_NAME;
#endif
 
int main()
{
  vpIN_FCT("main()");
  // the body of the main() function
  vpOUT_FCT("main()");
}

See also: vpOUT_FCT

Examples: tutorial-trace.cpp.

Definition at line 294 of file vpDebug.h.

◆ vpOUT_FCT

#define vpOUT_FCT (vpTraceOutput(__FILE__, __LINE__, __FUNCTION__, false, "end "))

Works like vpTRACE() and should be used at the end of a function.

#define VP_TRACE // To activate the trace mode
#include <visp3/core/vpDebug.h>
 
#ifdef ENABLE_VISP_NAMESPACE
using namespace VISP_NAMESPACE_NAME;
#endif
 
int main()
{
  vpIN_FCT("main()");
  // the body of the main() function
  vpOUT_FCT("main()");
}

◆ vpTRACE

#define vpTRACE (vpTraceOutput(__FILE__, __LINE__, __FUNCTION__, false))

Used to display trace messages on the standard stream. Prints the name of the file, the function name and the line where it was used. Use like this : vpTRACE("my debug message number %d", i); with any "printf" string.

#define VP_TRACE // To activate trace mode
#include <visp3/core/vpDebug.h>
