/* The <errno.h> header defines the numbers of the various errors that can
* occur during program execution. They are visible to user programs and
* should be small positive integers. However, they are also used within
* MINIX, where they must be negative. For example, the READ system call is
* executed internally by calling do_read(). This function returns either a
* (negative) error number or a (positive) number of bytes actually read.
*
* To solve the problem of having the error numbers be negative inside the
* the system and positive outside, the following mechanism is used. All the
* definitions are are the form:
*
* <define> EPERM (_SIGN 1 )
*
* If the macro _SYSTEM is defined, then _SIGN is set to "-", otherwise it is
* set to "". Thus when compiling the operating system, the macro _SYSTEM
* will be defined, setting EPERM to (- 1), whereas when when this
* file is included in an ordinary user program, EPERM has the value ( 1).
