readDecimalLong
Reads a long from this source in signed decimal form (i.e., as a string in base 10 with optional leading -
).
Source data will be consumed until the source is exhausted, the first occurrence of non-digit byte, or overflow happened during resulting value construction.
Throws
if the found digits do not fit into a long
or a decimal number was not present.
if the source is exhausted before a call of this method.
when the source is closed.

import kotlin.test.*
fun main() {
//sampleStart
val buffer = Buffer()
buffer.writeString("42 -1 1234567!")
assertEquals(42L, buffer.readDecimalLong())
buffer.skip(1) // skip space
assertEquals(-1L, buffer.readDecimalLong())
buffer.skip(1) // skip space
assertEquals(1234567L, buffer.readDecimalLong())
buffer.skip(1) // skip !
//sampleEnd
