FUNLOCKFILE(3S)                      SysV                      FUNLOCKFILE(3S)



NAME
     funlockfile - unlock a stdio stream

SYNOPSIS
     #include <stdio.h>

     void funlockfile (FILE * stream );

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 stream argument is not pointer to a valid
     FILE structure.
