Subclause [[syserr]](syserr "19.5 System error support") describes components that the standard library and
|
||
C++ programs may use to report error conditions originating from
|
||
the operating system or other low-level application program interfaces[.](#1.sentence-1)

Components described in [[syserr]](syserr "19.5 System error support") do not change the value oferrno ([[errno]](errno "19.4 Error numbers"))[.](#2.sentence-1)
|
||
|
||
*Recommended practice*: Implementations should leave the error states provided by other
|
||
libraries unchanged[.](#2.sentence-2)
