Removes an extended attribute.
Extended attributes are name:value pairs associated with the file system objects (such as files, directories, and symlinks). They are extensions to the normal attributes that are associated with all objects in the file system (that is, the stat(2) data).
Do not define an extended attribute name with the 8-character prefix "(0xF8)SYSTEM(0xF8)". Prefix "(0xF8)SYSTEM(0xF8)" is reserved for system use only.
The removeea subroutine removes the extended attribute identified by name and associated with the given path in the file system. The fremoveea subroutine is identical to removeea, except that it takes a file descriptor instead of a path. The lremoveea subroutine is identical to removeea, except, in the case of a symbolic link, the link itself is interrogated rather than the file that it refers to.
|path||The path name of the file.|
|name||The name of the extended attribute. An extended attribute name is a NULL-terminated string.|
|filedes||A file descriptor for the file.|
If the removeea subroutine succeeds, 0 is returned. Upon failure, -1 is returned and errno is set appropriately.
|EACCES||Caller lacks write permission on the base file, or lacks the appropriate ACL privileges for named attribute delete.|
|EFAULT||A bad address was passed for path or name.|
|EFORMAT||File system is capable of supporting EAs, but EAs are disabled.|
|EINVAL||A path-like name should not be used (such as zml/file, . and ..).|
|ENOATTR||The named attribute does not exist, or tthe process has no access to this attribute.|
|ENOTSUP||Extended attributes are not supported by the file system.|
