NAME

       zip_source_file - create data source from a file

LIBRARY

       libzip (-lzip)

SYNOPSIS

       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.
