Gnulib module: mkdir

|
|
When the argument ends in a slash, the function call fails on some platforms.
|
|
@item
|
|
This function mistakenly succeeds on @samp{mkdir("d/./",mode)} on
|
|
some platforms:
|
|
Cygwin 1.5.x, mingw.
|
|
@item
|
|
On Windows platforms (excluding Cygwin), this function is called @code{_mkdir}
|
|
and takes only one argument. The fix (without Gnulib) is to define a macro
|
|
like this:
|
|
@smallexample
|
|
#define mkdir ((int (*)()) _mkdir)
|
|
@end smallexample
|
|
or
|
|
@smallexample
|
|
#define mkdir(path,mode) _mkdir (path)
|
|
@end smallexample
