/* 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).
