57 The fifo's owner ID is set to the process's effective user ID.
58 The fifo's group ID is set to that of the parent directory in
66 will fail and no fifo will be created if:
69 The kernel has not been configured to support fifo's.

73 A component of a pathname exceeded 255 characters,
74 or an entire path name exceeded 1023 characters.
76 A component of the path prefix does not exist.
78 A component of the path prefix denies search permission, or write permission
79 is denied on the parent directory of the fifo to be created.
81 Too many symbolic links were encountered in translating the pathname.
83 The named file would reside on a read-only file system.
85 The named file exists.
87 The parent directory of the named file has its immutable flag set, see the
89 manual page for more information.
91 The directory in which the entry for the new fifo is being placed
92 cannot be extended because there is no space left on the file
93 system containing the directory.
95 There are no free inodes on the file system on which the
96 fifo is being created.
98 The directory in which the entry for the new fifo
99 is being placed cannot be extended because the
100 user's quota of disk blocks on the file system
101 containing the directory has been exhausted.
103 The user's quota of inodes on the file system on
104 which the fifo is being created has been exhausted.
108 error occurred while making the directory entry or allocating the inode.
112 error occurred while reading from or writing to the file system.
