## 5.6 Setting Options
## 5.6 Buffering Symbols in Memory (memfile)
Symbols can also be stored as "in-memory" file buffers by giving the
`BARCODE_MEMORY_FILE` option to the `output_options` member, which saves the
print output to member `memfile` instead of to the output file `outfile`. The
length of the buffer is given in `memfile_size`. For instance:
```c
#include <zint.h>
#include <stdio.h>
#include <string.h>
int main(int argc, char **argv)
{
struct zint_symbol *my_symbol;
my_symbol = ZBarcode_Create();
my_symbol->output_options |= BARCODE_MEMORY_FILE;
/* Only the extension is used, to determine output format */
strcpy(my_symbol->outfile, "mem.svg");
ZBarcode_Encode_and_Print(my_symbol, argv[1], 0, 0);
/* `my_symbol->memfile` now contains the SVG output */
fwrite(my_symbol->memfile, 1, my_symbol->memfile_size, stdout);
ZBarcode_Delete(my_symbol);
return 0;
}
```
will print the SVG output to `stdout` (the file "mem.svg" is not created). This
is particularly useful for the textual formats EPS and SVG,[^7] allowing the
output to be manipulated and processed by the client.
[^7]: BARCODE_MEMORY_FILE textual formats EPS and SVG will have Unix newlines
(LF) on both Windows and Unix, i.e. not CR+LF on Windows.
## 5.7 Setting Options
So far our application is not very useful unless we plan to only make Code 128
symbols and we don't mind that they only save to `"out.png"`. As with the CLI
program, of course, these options can be altered. The way this is done is by
altering the contents of the `zint_symbol` structure between the creation and
encoding stages. The `zint_symbol` structure consists of the following members:
