ZIP_FOPEN(3)		     Library Functions Manual		    ZIP_FOPEN(3)

NAME
     zip_fopen, zip_fopen_index -- open file in zip archive for reading

LIBRARY
     libzip (-lzip)

SYNOPSIS
     #include <zip.h>

     zip_file_t *
     zip_fopen(zip_t *archive, const char *fname, zip_flags_t flags);

     zip_file_t *
     zip_fopen_index(zip_t *archive, zip_uint64_t index, zip_flags_t flags);

DESCRIPTION
     The  zip_fopen()  function opens the file name fname in archive.  The flags
     argument specifies how the name lookup should be  done,  according  to  the
     values are described in zip_name_locate(3).  Also, the following values may
     be or'ed to it.

	   ZIP_FL_COMPRESSED  Read  the  compressed data.  Otherwise the data is
			      uncompressed by zip_fread().

	   ZIP_FL_UNCHANGED   Read the original data from the zip  archive,  ig-
			      noring  any  changes made to the file; this is not
			      supported by all data sources.

     The zip_fopen_index() function opens the file at position index.

     If encrypted data is encountered, the functions call zip_fopen_encrypted(3)
     or zip_fopen_index_encrypted(3) respectively, using  the  default	password
     set with zip_set_default_password(3).

RETURN VALUES
     Upon  successful completion, a struct zip_file pointer is returned.  Other-
     wise, NULL is returned and the error code in archive is set to indicate the
     error.

ERRORS
     [ZIP_ER_CHANGED]	The file data has been changed and the data source  does
			not support rereading data.

     [ZIP_ER_COMPNOTSUPP]
			The compression method used is not supported.

     [ZIP_ER_ENCRNOTSUPP]
			The encryption method used is not supported.

     [ZIP_ER_MEMORY]	Required memory could not be allocated.

     [ZIP_ER_NOPASSWD]	The  file  is  encrypted,  but no password has been pro-
			vided.

     [ZIP_ER_READ]	A file read error occurred.

     [ZIP_ER_SEEK]	A file seek error occurred.

     [ZIP_ER_WRONGPASSWD]
			The provided password does not match the  password  used
			for  encryption.  Note that some incorrect passwords are
			not detected by the check done by zip_fopen().

     [ZIP_ER_ZLIB]	Initializing the zlib stream failed.

     The function zip_fopen() may also fail and set zip_err for any of	the  er-
     rors specified for the routine zip_name_locate(3).

     The  function zip_fopen_index() may also fail with ZIP_ER_INVAL if index is
     invalid.
