ZIP_FDOPEN(3)		     Library Functions Manual		   ZIP_FDOPEN(3)

NAME
     zip_fdopen -- open zip archive using open file descriptor

LIBRARY
     libzip (-lzip)

SYNOPSIS
     #include <zip.h>

     zip_t *
     zip_fdopen(int fd, int flags, int *errorp);

DESCRIPTION
     The  zip  archive	specified by the open file descriptor fd is opened and a
     pointer to a struct zip, used to manipulate the archive, is  returned.   In
     contrast to zip_open(3), using zip_fdopen the archive can only be opened in
     read-only	mode.	The fd argument may not be used any longer after calling
     zip_fdopen.  The flags are specified by or'ing the following values,  or  0
     for none of them.

	   ZIP_CHECKCONS  Perform  additional stricter consistency checks on the
			  archive, and error if they fail.

     If an error occurs and errorp is non-NULL, it will be  set  to  the  corre-
     sponding error code.

RETURN VALUES
     Upon  successful  completion zip_fdopen() returns a struct zip pointer, and
     fd should not be used any longer, nor passed to close(2).	Otherwise,  NULL
     is  returned  and *errorp is set to indicate the error.  In the error case,
     fd remains unchanged.

ERRORS
     The file specified by fd is prepared for use by libzip(3) unless:

     [ZIP_ER_INCONS]	Inconsistencies were found  in	the  file  specified  by
			path.	 This	error  is  often  caused  by  specifying
			ZIP_CHECKCONS but can also happen without it.

     [ZIP_ER_INVAL]	The flags argument  is	invalid.   Not	all  zip_open(3)
			flags are allowed for zip_fdopen, see "DESCRIPTION".

     [ZIP_ER_MEMORY]	Required memory could not be allocated.

     [ZIP_ER_NOZIP]	The file specified by fd is not a zip archive.

     [ZIP_ER_OPEN]	The  file  specified by fd could not be prepared for use
			by libzip(3).

     [ZIP_ER_OPNOTSUPP]
			This functionality has been disabled at compile time.

     [ZIP_ER_READ]	A read error occurred; see errno for details.

     [ZIP_ER_SEEK]	The file specified by fd does not allow seeks.
