T-Kernel Specification (1.B0.02)

7.2. LIST OF ERROR CODES 289
E NOCOP ERCD(-6, 0) The designated coprocessor cannot be used (not installed, or abnormal operation
detected)
This error code is returned when the designated coprocessor is not installed in the currently
running hardware, or abnormal coprocessor operation was detected.
Unsupported Error Class (9 to 16)
E NOSPT ERCD(-9, 0) Unsupported function
When some system call functions are not supported and such a function was designated,
error code E RSATR or E NOSPTS is returned. If E RSATR does not apply, error code E NOSPT
is returned.
E RSFN ERCD(-10, 0) Reserved function code number
This error code is returned when it is attempted to execute a system call designating a
reserved function code (undefined function code), and also when it is attempted to execute
an undefined extended SVC handler.
E RSATR ERCD(-11, 0) Reserved attribute
This error code is returned when an undefined or unsupported object attribute is designated.
Checking for this error may be omitted if system-dependent optimization is implemented.
Parameter Error Class (17 to 24)
E PAR ERCD(-17, 0) Parameter error
Checking for this error may be omitted if system-dependent optimization is implemented.
E ID ERCD(-18, 0) Invalid ID number
E ID is an error that occurs only for objects having an ID number. Error code E PAR is
returned when a static error is detected such as designation of an out of range or reserved
number for an interrupt definition number.
Call Context Error Class (25 to 32)
E CTX ERCD(-25, 0) Context error
This error indicates that the designated system call cannot be issued in the current context
(task portion/task-independent portion or handler RUN state).
This error must be issued whenever there is a meaningful context error in issuing a system
call, such as calling from a task-independent portion a system call that may put the invoking
task in WAIT state. Due to implementation limitations, there may be other system calls
that when called from a given context (such as an interrupt handler) will cause this error to
be returned.
E MACV ERCD(-26, 0) Memory cannot be accessed; memory access privilege error
Error detection is implementation-dependent.
