mkdir
Author
weird problem.
i have a createFolder func that creates every folder one by one to the full path. for example "/opt/here/new fold/last/file.txt" would create opt if needed and work its way up to last.
Right now, it last is missing and everything up to exist. when i mkdir i get the error EEXIST as expected. When it finally gets to last i get ENOENT, WTF!?!
man 2 mkdir says
[ENOENT] A component of the path prefix does not exist or path
is an empty string.
everything before last exist, so... wtf?!
i tried using both /opt/here/new fold/last and /opt/here/new fold/last/ both get me that error. Whats going on?
I'm guessing you're using a recursive function... Could you post your code? Maybe you're traversing the list of folders to create backwards?

Nope, i have a fake mkdir for win32 and it works perfectly there.
I was using a fake mkdir that takes in 1 param (used for windows). I just realized it called mkdir(sz, 0), so maybe 0 is causing the problem?
PS: how do i find the error variable when i get the error value? i dont like doing what i did below.

size_t fs_createSubs(const char*sz){ std::string s = sz, s2; size_t pos=3; while (1) { size_t a, b, c; a = s.find("\\", pos); b = s.find("/", pos); c = min(a, b); if (c == -1u) break; pos = c+1; s2 = s.substr(0, c); // s2 += "/"; if (mkdir(s2.c_str(), 0)) { int a=errno, b; if (a == EEXIST) printf("%d\n", b); b++; if (a == EACCES) printf("%d\n", b); b++; if (a == EFAULT) printf("%d\n", b); b++; if (a == ELOOP) printf("%d\n", b); b++; if (a == ENAMETOOLONG) printf("%d\n", b); b++; if (a == ENOENT) printf("%d\n", b); b++; if (a == ENOMEM) printf("%d\n", b); b++; if (a == ENOSPC) printf("%d\n", b); b++; if (a == ENOTDIR) printf("%d\n", b); b++; if (a == EPERM) printf("%d\n", b); b++; if (a == EROFS) printf("%d\n", b); b++; } } return 0;}

I found the solution
It was an access error, i dont know why i got ENOENT instead of EACCES :|
It was an NTFS fs (im on mac) and i didnt realize i uninstall ntfs3g days before. (i forget what the problem was, i thought ntfs3g was tied to it, it wasnt)
installed it and my code works great.
