package bytes
ReadBytes reads until the first occurrence of delimiter in the input, returning a slice containing the data up to and including the delimiter. If ReadBytes encounters an error before finding a delimiter, it returns the data read before the error and the error itself (often io.EOF). ReadBytes returns err != nil if and only if the returned data does not end in the given delimiter.
Golang bytes.Buffer.ReadBytes() function usage example
package main
import (
"bytes"
"fmt"
)
func main() {
buff := bytes.NewBufferString("abcd*ef")
rb, err := buff.ReadBytes('*') // end with 's'.... plural!
fmt.Printf("%v %d %s\n", err, rb, string(rb))
}
Output :
[97 98 99 100 42] abcd*
