NAME

       zip_fopen , - .Nm zip_fopen_index open file in zip archive for reading

LIBRARY

       libzip (-lzip)

SYNOPSIS

       #include <zip.h>

       struct zip_file * zip_fopen(struct zip *archive, const char *fname, int flags);

       struct zip_file * zip_fopen_index(struct zip *archive, zip_uint64_t index, int 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,  ignoring  any
                                 changes made to the file.

       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.  Otherwise, 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.

              [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_READ]
                  A file read error occurred.

              [ZIP_ER_SEEK]

              [ZIP_ER_ZLIB]
                  Initializing the zlib stream failed.

       The function zip_fopen may also fail and set for any  of  the  errors  specified  for  the
       routine zip_name_locate(3).

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