## Detailed Description

Functions that deal with names.

A non-tail address of the program may have a name. Tail addresses (i.e. the addresses in the middle of an instruction or data item) cannot have names.

Set or delete name of an item at the specified address.

An item can be anything: instruction, function, data byte, word, string, structure, etc... Include name into the list of names.

Parameters

  ea | linear address. do nothing if ea is not valid (return 0). tail bytes can't have names.
  name | new name. nullptr: do nothing (return 0). "" : delete name. otherwise this is a new name.

Parameters

  [out] | out | output buffer for the name
  | from | linear address of instruction operand or data referring to the name. This address will be used to get fixup information, so it should point to exact position of the operand in the instruction.
  | n | number of referencing operand. for data items specify 0
  | ea | address to convert to name expression
  | off | the value of name expression. this parameter is used only to check that the name expression will have the wanted value. 'off' may be equal to BADADDR but this is discouraged because it prohibits checks.
