objective c - How to solve this error 'BIO_new' is deprecated in cocoa? -


i new macintosh development. have nsdata+connection.m file. file have more deprecated function bio_new , bio_write, bio_get_mem_data etc. functions encounter deprecated errors.

- (nsstring *)base64encoding {     bio * mem = bio_new(bio_s_mem());     bio * b64 = bio_new(bio_f_base64());     bio_set_flags(b64, bio_flags_base64_no_nl);     mem = bio_push(b64, mem);      bio_write(mem, [self bytes], [self length]);     bio_flush(mem);      char * base64pointer;     long base64length = bio_get_mem_data(mem, &base64pointer);      nsstring * base64string = [nsstring stringwithcstring:base64pointer                                                length:base64length];      bio_free_all(mem);     return base64string; }

please me.

what apple has deprecated using their openssl headers , their openssl dynamic library. reason openssl's interface changes in incompatible ways across minor revisions, it's hard keep date bugfixes , security updates without breaking client code.

what can (and have done in past) grab openssl yourself, use functions version , bundle application.

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...
