c++ - How to use X509_verify() -


how can use x509_verify(). have 2 certificates. first certificate root certificate signed next certificate (which certificate). want check if certificate signed root certificate using x509_verify() in c++. goal keep code simple , understandable can put online.

signature of x509_verify is

 int x509_verify(x509 * x509, evp_pkey * pkey);

suppose of have root certificate in root , certificate in mycert;

   x509 * root;    x509 * mycert;  //get root certificate root //get mycert mycert.  //get public key. evp_pkey * pubkey = x509_get_pubkey(root);  //verify. result less or 0 means not verified or error. int result = x509_verify(mycert, pubkey);  //free public key. evp_pkey_free(pubkey);

i think you.

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
