C programlama errno.h dosyası (kütüphanesi)

errno.H :errno sistem hatası değişkenini ve sistem çağrıları tarafından ayarlanan hata numaralarını unix'te bulunan ancak msdos değerinde olmayan hatalar tanımlar
_doserrno

errno

_sys_nerr

error number definitions

Aşağıdaki kodları not defterine yapıştırıp kaydet yaparken errno.h diye kaydedelim.

/*  errno.h

    Defines the system error variable errno and the error
    numbers set by system calls. Errors which exist in Unix(tm)
    but not MSDOS have value -1.
