Removes slave from the packing order for its master and unmaps its window. The slave will no longer be managed by the packer. If boolean has a false boolean value then propagation is disabled for master . In either of these cases an empty string is returned. If boolean is omitted then the command returns 0 or 1 to indicate whether propagation is currently enabled for master .
Propagation is enabled by default.
The order of the slaves in the list is the same as their order in the packing order. If master has no slaves then an empty string is returned. For each master the packer maintains an ordered list of slaves called the packing list . If none of these options is given for a slave then the slave is added to the end of the packing list for its parent. The packer arranges the slaves for a master by scanning the packing list in order.
