| 5 | .B mknod(name, mode, addr) | |
| 6 | .br | |
| 7 | .B char *name; | |
| 8 | .SH DESCRIPTION | |
| 9 | .I Mknod | |
| 10 | creates a new file | |
| 11 | whose name is the null-terminated string pointed | |
| 12 | to by | |
| 13 | .IR name . | |
| 14 | The mode of the new file | |
| 15 | (including directory and special file bits) | |
| 16 | is initialized from | |
| 17 | .IR mode . | |
| 18 | (The protection part of the mode | |
| 19 | is modified by the process's mode mask; see | |
| 20 | .IR umask (2)). | |
| 21 | The first block pointer of the i-node | |
| 22 | is initialized from | |
| 23 | .IR addr . | |
| 24 | For ordinary files and directories | |
| 25 | .I addr | |
| 26 | is normally zero. | |
| 27 | In the case of a special file, | |
| 28 | .I addr | |
| 29 | specifies which special file. | |
| 30 | .PP | |
| 31 | .I Mknod | |
| 32 | may be invoked only by the super-user. | |
