find home directory c++

i am using curl in my program and i need to be able to find the current users home directory, here is a snippet of the curl procedure

char *headerfilename = "logfile";
FILE *headerfile;
headerfile = fopen(headerfilename,"w");
curl_easy_setopt(curl_handle,   CURLOPT_WRITEHEADER ,headerfile);

i need that headerfilename to be /home/USERNAME/logfile

any help would be great

Thanks

or u can try this too.

char *name;
name = (char *)malloc(sizeof(char)*(PATH_MAX));
name = getcwd(name,PATH_MAX);
