NAME

       zip_source_file, zip_source_file_create — create data source from a file

LIBRARY

       libzip (-lzip)

SYNOPSIS

       #include <zip.h>

       zip_source_t *
       zip_source_file(zip_t *archive, const char *fname, zip_uint64_t start, zip_int64_t len);

       zip_source_t *
       zip_source_file_create(const char *fname, zip_uint64_t start, zip_int64_t len, zip_error_t *error);

DESCRIPTION

       The  functions zip_source_file() and zip_source_file_create() create a zip source from a file.  They open
       fname and read len bytes from offset start from it.  If len is 0 or -1, the  whole  file  (starting  from
       start) is used.

       If the file supports seek, the source can be used to open a zip archive from.

       The  file  is  opened  and  read  when  the  data  from  the  source  is  used, usually by zip_close() or
       zip_open_from_source().

RETURN VALUES

       Upon successful completion, the created source is returned.  Otherwise, NULL is returned  and  the  error
       code in archive or error is set to indicate the error.

ERRORS

       zip_source_file() and zip_source_file_create() fail if:

       [ZIP_ER_INVAL]     fname, start, or len are invalid.

       [ZIP_ER_MEMORY]    Required memory could not be allocated.

       [ZIP_ER_OPEN]      Opening fname failed.
