通过WIN32宏进行判断
 
window下mkdir函数
 
#include<direct.h>
int _mkdir( const char *dirname );
 
linux下mkdir函数mode_t参数详解

#include <sys/stat.h>
int mkdir(const char *path, mode_t mode);
 
参数:
path是目录名
mode是目录权限

返回值:
返回0 表示成功, 返回 -1表示错误,并且会设置errno值。

mode模式位:
mode 表示新目录的权限,可以取以下值:
S_IRUSR 
S_IREAD
S_IWUSR 
S_IWRITE 
S_IXUSR 
S_IEXEC 
S_IRWXU 
This is equivalent to (S_IRUSR | S_IWUSR | S_IXUSR). 
S_IRGRP 
Read permission bit for the group owner of the file. Usually 040. 
S_IWGRP 
Write permission bit for the group owner of the file. Usually 020. 
S_IXGRP 
Execute or search permission bit for the group owner of the file. Usually 010. 
S_IRWXG 
This is equivalent to (S_IRGRP | S_IWGRP | S_IXGRP). 
S_IROTH 
Read permission bit for other users. Usually 04. 
S_IWOTH 
Write permission bit for other users. Usually 02. 
S_IXOTH 
Execute or search permission bit for other users. Usually 01. 
S_IRWXO 
This is equivalent to (S_IROTH | S_IWOTH | S_IXOTH). 
S_ISUID 
This is the set-user-ID on execute bit, usually 04000. See How Change Persona. 
S_ISGID 
This is the set-group-ID on execute bit, usually 02000. See How Change Persona. 
S_ISVTX 
This is the sticky bit, usually 01000.
 
S_IRWXU 00700权限,代表该文件所有者拥有读,写和执行操作的权限
S_IRUSR(S_IREAD) 00400权限,代表该文件所有者拥有可读的权限
S_IWUSR(S_IWRITE) 00200权限,代表该文件所有者拥有可写的权限
S_IXUSR(S_IEXEC) 00100权限,代表该文件所有者拥有执行的权限
S_IRWXG 00070权限,代表该文件用户组拥有读,写和执行操作的权限
S_IRGRP 00040权限,代表该文件用户组拥有可读的权限
S_IWGRP 00020权限,代表该文件用户组拥有可写的权限
S_IXGRP 00010权限,代表该文件用户组拥有执行的权限
S_IRWXO 00007权限,代表其他用户拥有读,写和执行操作的权限
S_IROTH 00004权限,代表其他用户拥有可读的权限
S_IWOTH 00002权限,代表其他用户拥有可写的权限
S_IXOTH 00001权限,代表其他用户拥有执行的权限
 
例子:
#include <sys/types.h> #include <sys/stat.h> 
int status;
status = mkdir("/home/newdir", S_IRWXU | S_IRWXG | S_IROTH | S_IXOTH);
这样就创建了一个newdir目录,权限通过ls -al 查看为
drwxr-xr-x
跟用linux命令mkdir创建的目录权限位一致。
