getcwd

问题 I am trying to compile ARM code in Ubuntu 12. Everything is working fine when I put the code in the local directory. But when I put the code in cited mount directory error shows up: making testXmlFiles sh: 0: getcwd() failed: No such file or directory ARM Compiling xxxxx.c sh: 0: getcwd() failed: No such file or directory Here is my setting in fstab //10.0.0.1/data /mnt/data cifs auto,noserverino,credentials=/root/.smbcredentials,file_mode=0777,dir_mode=0777,uid=user,gid=users,noperm 0 0 What

问题 Does anyone have an idea how to get the current working directory in OSX with NASM? The syscall getcwd isn't available on osx and dtruss pwd return lots of stat sys calls. However in the manual I can't find which structure variable of stat returns the current working directory. Thanks. 回答1: That's a bit late answer, but nonetheless this can be achieved using 2 syscalls. open_nocancel 0x2000018e (or open 0x2000005) opening a file descriptor for current dir fcntl_nocancel 0x20000196 (or fcntl

问题 I have just noticed that getcwd() return "/" if called within __destruct() magic function, while in any other method it returns the expected path. Do you have an explanation for this? 回答1: It's a SAPI behaivor "Destructors called during the script shutdown have HTTP headers already sent. The working directory in the script shutdown phase can be different with some SAPIs (e.g. Apache)." From http://php.net/manual/en/language.oop5.decon.php But as mentioned in other answers there are plenty

问题 What's the Lua to get the current working directory on Windows XP SP3 (or to get the directory of the currently-running Lua file)? I prefer not to use LuaFileSystem. I can't use os.execute("cd") because os.execute always starts from my home directory (and thus always yields C:\Documents and Settings\username ). 回答1: Lua by default doesn't have a "native" way of supporting the concept of "current directory", or, in fact, the concept of "directory". The proper way to get the current directory

问题 I get a warning warning: comparison between pointer and integer on the line containing if from the next piece of code: char cwd[1024]; if (getcwd(cwd, sizeof(cwd)) != (char*)NULL) printf("%s\n",cwd); else error_print("error in pwd"); how and what do I need to fix? 回答1: Do you include unistd.h? If not, the error appears because your C compiler is assuming getcwd returns int. The fix? Include unistd.h 回答2: The prototype of getcwd is char *getcwd(char *buf, size_t size); Make sure you include

问题 Sorry to keep hammering on this, but I'm trying to learn :). Is this any good? And yes, I care about memory leaks. I can't find a decent way of preallocating the char*, because there simply seems to be no cross-platform way. const string getcwd() { char* a_cwd = getcwd(NULL,0); string s_cwd(a_cwd); free(a_cwd); return s_cwd; } UPDATE2: without Boost or Qt, the most common stuff can get long-winded (see accepted answer) 回答1: If you want to remain standard, getcwd isn't required to do anything

问题 I need a cross-platform way to get the current working directory (yes, getcwd does what I want). I thought this might do the trick: #ifdef _WIN32 #include <direct.h> #define getcwd _getcwd // stupid MSFT "deprecation" warning #elif #include <unistd.h> #endif #include <string> #include <iostream> using namespace std; int main() { string s_cwd(getcwd(NULL,0)); cout << "CWD is: " << s_cwd << endl; } I got this reading: _getcwd at MSDN getcwd at Kernel.org getcwd at Apple.com There should be no
