However, in the event that the same file descriptor number is allocated by some other operation (such as <i>dup</i>(), <i>fopen</i>(), <i>open</i>(), <i>pipe</i>(), <i>socket</i>(), and so forth), before <i>fclose</i>() is called, the <i>fclose</i>() call will close this newly allocated file descriptor instead. Therefore, applications which close the file descriptor before calling <i>fclose</i>() should ensure that they do not perform any file open operations in between closing the file descriptor and calling <i>fclose</i>(). This also applies in the event that two streams have the same associated file descriptor; calling <i>fclose</i>() on the first stream closes the file descriptor associated with both streams, and then calling <i>fclose</i>() on the second stream has the same risk described above. See also xref to P522, L18532 XSH 2.5.1 Interaction of File Descriptors and Standard I/O Streams.</blockquote> After page 918 line 31349, add to fdopen() APPLICATION USAGE:<blockquote>See also the APPLICATION USAGE for <i>fclose</i>().</blockquote> Issue History Date Modified Username Field Change ====================================================================== 2024-02-10 17:41 alanc New Issue 2024-02-10 17:41 alanc Name => Alan Coopersmith 2024-02-10 17:41 alanc Organization => Oracle Solaris Engineering 2024-02-10 17:41 alanc Section => fdopen() 2024-02-10 17:41 alanc Page Number => 917 2024-02-10 17:41 alanc Line Number => 31300-31397 2024-02-10 18:57 Don Cragun Relationship added related to 0001809 2024-02-12 19:09 alanc Note Added: 0006652 2024-04-11 11:02 geoffclare Note Added: 0006744 2024-04-11 20:48 alanc Note Added: 0006749 2024-04-15 15:59 geoffclare Note Added: 0006750 ======================================================================
