[Doxygen-users] Doxygen to identify an extra attribute

[Weng, J. <Jia...@av...>]

Hello,

I have a question about doxygen to retrieve the information from C source code.

Is it possible to identify an attribute like read-only, write-only, read-write for a global variable when it is referenced or updated in a function by doxygen?

For example,

/* 4 sides of the AOT databases parameters in the voting structure compare to each others,
* and the following 6 varieties indicate each compare results of each compare group. */
static UINT32 zero_oneConst;
static UINT32 one_twoConst;


static void  aot2Outof3 (void* bufAdrs_0, void* bufAdrs_1,
                                                                                void* bufAdrs_2, ULONG cmpSize,
                                                                                VOTE_MINOR_TYPE *pVoteMinor
                                                                                )
{

                zero_oneConst = memcmp(bufAdrs_0, bufAdrs_1, cmpSize);
                one_twoConst = memcmp(bufAdrs_1, bufAdrs_2, cmpSize);

                if((zero_oneConst == 0U) && (one_twoConst == 0U) )
                {
                       *pVoteMinor = NO_MINOR;
                 }

        ....

}

static void aot3Outof4 (void* bufAdrs_0, void* bufAdrs_1,
                                               )
{

                two_threeConst  = memcmp(bufAdrs_2, bufAdrs_3, cmpSize);


                if((zero_oneConst == 0U) && (one_twoConst == 0U) && (two_threeConst == 0U) )
                {
                         *pVoteMinor = NO_MINOR;
                  }
 ...
}

How can we identify global variable zero_oneConst and one_twoConst are read_write in function aot2Outof3() but they are read-only in function aot3Outof4()?

Thanks,
Jian Weng
