This article mainly introduces "what is the difference between Linux's mkdir function and Windows's mkdir function". In daily operation, I believe many people have doubts about the difference between Linux's mkdir function and Windows's mkdir function. Xiaobian consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the question of "what is the difference between the mkdir function of Linux and the mkdir function of Windows?" Next, please follow the editor to study!

Let's first introduce the _ mkdir function under windows.

The copy code is as follows:

# include

Int _ mkdir (const char * dirname)

Parameters:

Dirname is the pathname pointer to the directory

Return value:

If the creation time of the new directory, each of these functions returns a value of 0. In error, the function returns-1

Detailed explanation of mode_t parameters of mkdir function under linux

The copy code is as follows:

# include

Int mkdir (const char * path, mode_t mode)

Parameters:

Path is the directory name

Mode is a directory permission

Return value:

Returning 0 indicates success,-1 indicates error, and the errno value is set.

Mode mode bits:

Mode represents the permissions of the new directory. You can take the following values:

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 permissions, which means that the owner of the file has permission to read, write, and perform operations

S_irusr (s_iread) 00400 permissions, indicating that the owner of the file has readable permissions

S_iwusr (s_iwrite) 00200 permissions, which means that the owner of the file has writable permissions

S_ixusr (s_iexec) 00100 permissions, which means that the owner of the file has the permission to execute

S_irwxg 00070 permissions, which means that the file user group has permission to read, write, and perform operations

S_irgrp 00040 permissions, which means that the file user group has readable permissions

S_iwgrp 00020 permissions, which means that the file user group has writable permissions

S_ixgrp 00010 permissions, which means that the file user group has the permission to execute

S_irwxo 00007 permissions, which means that other users have read, write, and perform operations

S_iroth 00004 permissions, which means that other users have readable permissions

S_iwoth 00002 permissions, which means that other users have writable permissions

S_ixoth 00001 permissions, which means that other users have the right to execute

Next, I will give you a detailed introduction of the mkdir function in linux.

Mkdir function

Header file library:

# include

# include

Function prototype:

Int mkdir (const char * pathname, mode_t mode)

Function description:

The mkdir () function creates a directory named after the parameter pathname in mode, and mode defines the permissions for the newly created directory.

Return value:

If the directory is created successfully, 0 is returned; otherwise-1 is returned and the error is logged to the global variable errno.

Mode mode:

S_irwxu 00700 permissions, which means that the owner of the file has permission to read, write, and perform operations

S_irusr (s_iread) 00400 permissions, indicating that the owner of the file has readable permissions

S_iwusr (s_iwrite) 00200 permissions, which means that the owner of the file has writable permissions

S_ixusr (s_iexec) 00100 permissions, which means that the owner of the file has the permission to execute

S_irwxg 00070 permissions, which means that the file user group has permission to read, write, and perform operations

S_irgrp 00040 permissions, which means that the file user group has readable permissions

S_iwgrp 00020 permissions, which means that the file user group has writable permissions

S_ixgrp 00010 permissions, which means that the file user group has the permission to execute

S_irwxo 00007 permissions, which means that other users have read, write, and perform operations

S_iroth 00004 permissions, which means that other users have readable permissions

S_iwoth 00002 permissions, which means that other users have writable permissions

S_ixoth 00001 permissions, which means that other users have the right to execute
