Is this case is normal when programming in socket?
My program has two threads, one is for sender and another one is receiver,

  1. The receiver loop forever and accept and receive data from sender.
  2. The sender may send message if necessary and terminated when the job finished (I create a new thread when new service is needed).
Now I have 2 questions, the first one is that when I use Ctrl+C to terminate my program, and use netstat -an command to see the network connection, I saw some connections are still here and their status are ESTABLISHED, is it normal?

mdbfontencoding

mdbFontEncoding(5)						 The m17n Library						mdbFontEncoding(5)

NAME

       mdbFontEncoding - Font Encoding

DESCRIPTION

       The m17n library loads information about the encoding of each font form the m17n database by the tags <font, encoding>. The data is loaded
       as a plist of this format.

       FONT-ENCODING ::= PER-FONT *

       PER-FONT ::= '(' FONT-SPEC ENCODING [ REPERTORY ] ')'

       FONT-SPEC ::=
	   '(' [ FOUNDRY FAMILY
	      [ WEIGHT [ STYLE [ STRETCH [ ADSTYLE ]]]]]
	    REGISTRY ')'

       ENCODING ::= SYMBOL

       FONT-SPEC is to specify properties of a font. FOUNDRY to REGISTRY are symbols corresponding to Mfoundry to Mregistry property of a font.
       See m17nFont for the meaning of each property.

       For instance, this FONT-SPEC:

	   (nil alice0 lao iso8859-1)

       should be applied to all fonts whose family name is 'alice0 lao', and registry is 'iso8859-1'.

       ENCODING is a symbol representing a charset. A font matching FONT-SPEC supports all characters of the charset, and a character code is
       mapped to the corresponding glyph code of the font by this charset.

       REPERTORY is a symbol representing a charset or 'nil'. Omitting it is the same as specifying ENCODING as REPERTORY. If it is not 'nil', the
       charset specifies the repertory of the font, i.e, which character it supports. Otherwise, whether a specific character is supported by the
       font or not is asked to each font driver.

       For so called Unicode fonts (registry is 'iso10646-1'), it is recommended to specify 'nil' as REPERTORY because such fonts usually supports
       only a subset of Unicode characters.
