objective c - xmlNewCDataBlock implicit conversion to int -


i'm parsing xml via libxml2 library. after updating xcode 5.1, got warning last parameter - length - implicitly converted int, while it's unsigned long. here's function declaration:

xmlpubfun xmlnodeptr xmlcall     xmlnewcdatablock(xmldocptr doc,                      const xmlchar *content,                      int len);

is there similar function takes unsigned long values, because don't know how big data can be, , want process safely.

there's no such function. libxml2's string manipulation functions use ints string lengths , offsets, text nodes longer int_max not supported.

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
