# binarypatch
Storing & retrieving arbitrary data from program headers
## Usage
Appending some data to an OSX/Darwin program:
```
package main
import(
"github.com/matiasinsaurralde/binarypatch"
)
func main() {
b := binarypatch.New( "myprogram", "darwin" )
index := b.Locate()
b.Write( []byte("hello"), index )
b.WriteFile( "myprogram_with_data")
}
```
```myprogram``` does the following:
```
package main
import(
"fmt"
"github.com/matiasinsaurralde/binarypatch"
)
func main() {
b := binarypatch.ReadMyself(5, -1, "darwin")
fmt.Println("Reading from myself: ", b, string(b) )
}
```
The output of the original program is:
```
% ./myprogram
Reading from myself: [0 0 0 0 0]
```
Then, the output of the "patched" program:
```
% ./myprogram_with_data
Reading from myself: [104 101 108 108 111] hello
```
