I have a thread dumping data to separate files, then every 5 minutes I
want to use libcurl to transfer the files to a server to be processed.
After a successful transfer I want to delete the file.

The code I currently have transfers files just fine, but when I try to
delete them after a transfer, the first file I list gets transferred
then deleted and then my program hangs.

Here is the code I'm using:

void curlFilesToServer(void){
        DIR *d;
        struct dirent *pdirent;
        char absPath[100] = "";
        char newPath[103] = "./";
        int retVal;
        
        //now curl it to a remote server
        struct curl_httppost* post = NULL;
        struct curl_httppost* last = NULL;
        CURL *hCURL = curl_easy_init();
        
        d = opendir(logdir);
        while ( (pdirent = readdir(d)) != NULL ){
                if(!strcmp(pdirent->d_name, ".") || !strcmp(pdirent->d_name, ".."))
continue;
                if(!strcmp(filename, pdirent->d_name)) continue;
                //printf("%s\n", pdirent->d_name);
                strcpy(absPath, logdir);
                strcat(absPath, pdirent->d_name);

                curl_easy_setopt(hCURL, CURLOPT_URL, "http://stuff.com/test.php");
                curl_formadd(&post, &last, CURLFORM_COPYNAME, "user",
CURLFORM_COPYCONTENTS, login, CURLFORM_END);
                curl_formadd(&post, &last, CURLFORM_COPYNAME, "pass",
CURLFORM_COPYCONTENTS, pword, CURLFORM_END);
                curl_formadd(&post, &last, CURLFORM_COPYNAME, "tracefile",
CURLFORM_FILE, absPath, CURLFORM_END);
                curl_easy_setopt(hCURL, CURLOPT_HTTPPOST, post);
                retVal = curl_easy_perform(hCURL);
                
                newPath[2] = '\0';
                strcat(newPath, absPath);

                if( retVal == 0 )
                {
                        unlink(newPath);
                        printf("newPath=%s\n", newPath);
                }
        }
}

I'm wondering if the curl_formadd is keeping the file descriptor open
and this is messing up the unlink(). All the files list properly when I
don't try to delete and just list them instead.
