removexattr
Removes the specified extended attribute from a file.
int removexattr ( const char *path, const char *name );
On success, returns zero. On failure, returns -1 and errno is set appropriately.
Extended attributes are name value pairs that are associated with files, directories, symbolic links, etc. They are extensions to the normal attributes that are associated with all files in the system.
An extended attribute name is a simple NULL-terminated string. The name includes a namespace prefix. There might be several namespaces associated with an individual extended attribute.
IMPORTANT:This function does not remove the netware.metadata extended attribute, but it does remove all the trustees and directory space restrictions associated with the file or directory.
