objective c - get socket from Stream -


i using following code open stream sends files ftp. need socket out of can implement second code posted here.

    self.networkstream = cfbridgingrelease(                                            cfwritestreamcreatewithftpurl(null, (__bridge cfurlref) url)                                            );     assert(self.networkstream != nil);      if ([usernametext length] != 0) {         success = [self.networkstream setproperty:usernametext forkey:(id)kcfstreampropertyftpusername];         assert(success);         success = [self.networkstream setproperty:passwordtext forkey:(id)kcfstreampropertyftppassword];         assert(success);     }      self.networkstream.delegate = self;     [self.networkstream setproperty:(id)kcfbooleanfalse forkey:(id)kcfstreampropertyftpattemptpersistentconnection];     [self.networkstream setproperty:(id)kcfbooleantrue forkey:(id)kcfstreampropertyshouldclosenativesocket];      [self.networkstream scheduleinrunloop:[nsrunloop currentrunloop] formode:nsdefaultrunloopmode];     [self.networkstream open];

.

cfsocketref cfsock = [sock getcfsocket];  cfsocketnativehandle rawsock = cfsocketgetnative(cfsock);  int flag = 1;  int result = setsockopt(rawsock, ipproto_tcp, tcp_nodelay,                     (char *)&flag, sizeof(int));  if (result != 0)     nslog(@\"could not disable nagle...\"); else     nslog(@\"nagle disabled.\");

second block requires socket in order executed , have stream , dont know how socket out of stream.

thanks

call cfwritestreamcopyproperty() on write stream , specify kcfstreampropertysocketnativehandle cfdataref containing underlying cfsocketnativehandle. can extract socket cfdatagetbytes().

cfsocketnativehandle rawsock; cfdataref socketdata =   cfwritestreamcopyproperty((__bridge cfwritestreamref)(self.networkstream),                             kcfstreampropertysocketnativehandle); cfdatagetbytes(socketdata,                cfrangemake(0, sizeof(cfsocketnativehandle)),                (uint8 *)&rawsock); cfrelease(socketdata);  /* make use of rawsock */

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
