NAME

       zip_fdopen - open zip archive using open file descriptor

LIBRARY

       libzip (-lzip)

SYNOPSIS

       #include <zip.h>

       struct zip * 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 the archive can only be opened in read-only
       mode.  The fd argument may not be used any longer after calling The are specified by or'ing the following values, or 0 for none of them.

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

       If an error occurs and errorp is it will be set to the corresponding 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  indi-
       cate the error.	In the error case, fd remains unchanged.
