Editing Incubator escapee wiki:WikiProject C/errno.h

'''errno.h''' is a [[header file]] component of a [[POSIX]] compliant [[operating system]] such as [[Unix|UNIX]] or [[Linux]]. Its function is to list operating system error code numbers, English code words, and comments.  A cut-down version of errno.h is also required by the [[C programming language|C]] standard.

On [[December 19]], [[2003]] the [[SCO_Group|SCO Group]] issued [[Digital_Millennium_Copyright_Act|DMCA]] notices to selected [[Fortune 1000]] companies, alleging the errno.h file was copied from UNIX into Linux without authorisation. [[Linus Torvalds]], the creator and trademark holder of Linux, has denied SCO's claim, saying he wrote the code himself.
