    1 /* The <errno.h> header defines the numbers of the various errors that can
    2  * occur during program execution.  They are visible to user programs and 
    3  * should be small positive integers.  However, they are also used within 
    4  * MINIX, where they must be negative.  For example, the READ system call is 
    5  * executed internally by calling do_read().  This function returns either a 
    6  * (negative) error number or a (positive) number of bytes actually read.
    7  *
    8  * To solve the problem of having the error numbers be negative inside the
    9  * the system and positive outside, the following mechanism is used.  All the
   10  * definitions are are the form:
   11  *
   12  *      #define EPERM           (_SIGN 1)
   13  *
   14  * If the macro _SYSTEM is defined, then  _SIGN is set to "-", otherwise it is
   15  * set to "".  Thus when compiling the operating system, the  macro _SYSTEM
   16  * will be defined, setting EPERM to (- 1), whereas when when this
   17  * file is included in an ordinary user program, EPERM has the value ( 1).
