Error in doxygen creation - c++

Question

I am using doxygen in my c++ project for generating documentation. My project contains both class functions and procedural calls like,
//AAA.h
namespace NAME
{
Class EXPORT AAA
{
/*!
* \brief Sample function.
*
* \param a is an integer value.
*
* This is a sample function.
*/
void SampleFunction(int a);
}
}'
after building this this code the doxygen is working fine and getting a detailed documentation.
But when i tried this with a procedural call like,
//BBB.h
namespace NAME2
{
/*!
* \brief This is a function
*
* \param b is a float
*
* This is a function
*/
void function(float b);
}
After building the code the document creates but missing the html file for its description, ie,
the doxygen creates with function name with brief statement.But when i click the function name it shows that html file is missing for the function description. And following is the doxyfile for the doxygen in my project. For generating the entire docs which field is to be changed in the doxyfile?

Answer 1

From the doxygen FAQ:
When I set EXTRACT_ALL to NO none of my functions are shown in the documentation.
In order for global functions, variables, enums, typedefs, and defines to be documented you should document the file in which these commands are located using a comment block containing a \file (or #file) command.
For member functions or functions that are part of a namespace you should document either the class or namespace.
Can you check that you have included a \file command in the file BBB.h or try documenting the namespace NAME2?

Answer 2

If EXTRACT_ALL=YES does not work, try to format the doc as following:
// Format:
/**
*
*/
// ex:
//BBB.h
namespace NAME2
{
/**
* \brief This is a function
*
* \param b is a float
*
* This is a function
*/
void function(float b);
}
