   46 .Fn zip_source_buffer_create "const void *data" "zip_uint64_t len" "int freep" "zip_error_t *error"
   47 .Sh DESCRIPTION
   48 The functions
   49 .Fn zip_source_buffer
   50 and
   51 .Fn zip_source_buffer_create
   52 create a zip source from the buffer
   53 .Ar data
   54 of size
   55 .Ar len .
   56 If
   57 .Ar freep
   58 is non-zero, the buffer will be freed when it is no longer needed.
   59 .Ar data
   60 must remain valid for the lifetime of the created source.
   61 .Pp
   62 The source can be used to open a zip archive from.
   63 .Sh RETURN VALUES
   64 Upon successful completion, the created source is returned.
   65 Otherwise,
   66 .Dv NULL
   67 is returned and the error code in
   68 .Ar archive
   69 or
   70 .Ar error
   71 is set to indicate the error.
   72 .Sh ERRORS
   73 .Fn zip_source_buffer
   74 and
