NAME

  funlockfile - Unlocks a stdio stream


LIBRARY

  Standard C Library (libc.a)


SYNOPSIS

  #include <stdio.h>
  void funlockfile(
	  FILE * file);


STANDARDS

  Interfaces documented on this reference page conform to industry standards
  as follows:

  funlockfile,	 POSIX.1c

  Refer to the standards(5) reference page for more information about
  industry standards and associated tags.


PARAMETERS

  file Specifies the stream to be unlocked.


DESCRIPTION

  The funlockfile() function unlocks a stdio stream, causing the thread that
  had been holding the lock to relinquish exclusive use of the stream.

  Matching flockfile() and funlockfile() calls can be nested.  If the stream
  has been locked recursively, then it will remain locked until the last
  matching funlockfile() is called.

  Behavior is unspecified if the file parameter is not pointer to a valid
  FILE structure.
