C语言创建路径函数头文件：direct.h或者wchar.h 函数原型：int _wmkdir(const wchar_t *dirname );
函数功能：创建一个目录，若成功则返回０，否则返回-1
类似函数：_mkdir，它的函数类型同_wmkdir，不过_mkdir只能使用direct.h作为头文件。
程序举例[1]来自MSDN的例子：// crt_makedir.c
#include <direct.h>
#include <stdlib.h>
#include <stdio.h>
int main( void )
{
if( _mkdir( "\testtmp" ) == 0 )
{
printf( "Directory '\testtmp' was successfully created
" );
system( "dir \testtmp" );
if( _rmdir( "\testtmp" ) == 0 )
printf( "Directory '\testtmp' was successfully removed
" );
else
printf( "Problem removing directory '\testtmp'
" );
}
else
printf( "Problem creating directory '\testtmp'
" );
}
