-Write the string into buffer and read it back out again.<br>
-<source lang="c">
-char blahsrc[]="this is blah";
-char blahdst[0x20];
-int putcnt, getcnt;
-//create 32 byte long rng buffer
-RING_ID rid=rngCreate(0x20);
-//write bytes into ring buffer
-putcnt=rngBufPut(rid, blahsrc, strlen(blahsrc)+1);
-//read bytes back out of ring buffer
-getcnt=rngBufGet(rid, blahdst, sizeof(blahdst));
-printf("put %d bytes into buffer, read %d bytes out: %s\n",putcnt,getcnt,blahdst);
