insertLen

fun insertLen(pos: Long, val: String, len: Long): String

Inserts @len bytes of @val into @string at @pos.

If @len is positive, @val may contain embedded nuls and need not be nul-terminated. It is the caller's responsibility to ensure that @val has at least @len addressable bytes.

If @len is negative, @val must be nul-terminated and @len is considered to request the entire string length.

If @pos is -1, bytes are inserted at the end of the string.

Return

@string

Parameters

pos

position in @string where insertion should happen, or -1 for at the end

val

bytes to insert

len

number of bytes of @val to insert, or -1 for all of @val
