The contents of the header <cerrno> are the same as the POSIX header[<errno.h>](support.c.headers.general#header:%3cerrno.h%3e "17.15.1 General [support.c.headers.general]"), except that errno shall be defined as a macro[.](#general-1.sentence-1)
|
||
|
||
[*Note [1](#general-note-1)*:
|
||
|
||
The intent is to remain in close alignment with the POSIX standard[.](#general-1.sentence-2)

|

A separate errno value is provided for each thread[.](#general-1.sentence-3)
