What is the difference between mkdir function in Linux and Windows

Copy code The code is as follows:

#include<direct.h>
int _mkdir( const char *dirname );

Parameters:

dirname is the pathname pointer of the directory

Return value:

Each of these functions returns a value of 0 if the new directory was created. In error, the function returns – 1

Detailed explanation of mode_t parameters of mkdir function under Linux

Copy code The code is as follows:

#include <sys/stat.h>
int mkdir(const char *path, mode_t mode);

Parameters:

path is the directory name

mode is the directory permissions

Return value:

Returns 0 for success, returns -1 for success error, and the errno value will be set.

mode mode bit:

mode represents the permissions of the new directory, which 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 the permissions to read, write and perform operations
s_irusr(s_iread) 00400 permissions, which means that the owner of the file has read permissions
s_iwusr(s_iwrite ) 00200 permissions, which means that the file owner has writable permissions
s_ixusr(s_iexec) 00100 permissions, which means that the file owner has execution permissions
s_irwxg 00070 permissions, which means that the file user group has read, write and Permissions to 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 readable permissions Have execution permissions
s_irwxo 00007 permissions, representing other users to have the permissions to read, write and execute operations
s_iroth 00004 permissions, representing other users to have readable permissions
s_iwoth 00002 permissions, representing other users to have the permissions to perform operations Write permission
s_ixoth 00001 permission, which means other users have execution permission

The following will give you a detailed introduction to the mkdir function in Linux

mkdir function

Header file library:

#include
#include

Function prototype:

int mkdir(const char *pathname, mode_t mode);

Function description:

mkdir() function starts with Mode mode creates a directory named with the parameter pathname, and mode defines the permissions of the newly created directory.

Return value:

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

mode mode:

s_irwxu 00700 permission, which means that the owner of the file has the permission to read, write and execute operations
s_irusr(s_iread) 00400 Permissions, which means 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 executable permissions Permissions
s_irwxg 00070 permissions, which means that the file user group has the permissions 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 readability permissions The group has writable permissions
s_ixgrp 00010 permissions, which means that the user group has execution permissions on the file
s_irwxo 00007 permissions, which means other users have the permissions to read, write and execute operations
s_iroth 00004 permissions, which represents other users The user has readable permissions
s_iwoth 00002 permissions, which means other users have writeable permissions
s_ixoth 00001 permissions, which means other users have execution permissions
