Documentation for method readchars
assembled from the following types:
class IO::CatHandle
From IO::CatHandle
(IO::CatHandle) method readchars
Defined as:
method readchars(IO::CatHandle: Int(Cool) = 65536 --> Str)
Returns a Str of up to $chars
characters read from the handle. $chars
defaults to an implementation-specific value (in Rakudo, the value of $*DEFAULT-READ-ELEMS
, which by default is set to 65536
). It is NOT permitted to call this method on handles opened in binary mode and doing so will result in X::IO::BinaryMode
exception being thrown.
