Translating MQX error codes

waynehawthorne — Thu, 22 Nov 2012 13:56:02 GMT

Hello...

I've been searching through the various fora and the documentation and I can't seem to find the answer I'm looking for.

I'm running code that has a call to _task_get_error(). Most of the time, this returns 0, however, in some calls, I see a different error code produced. How do you translate the error code to a useable statement? Other RTOS's provide either a .h file or a function that translates system error codes to human-readable statements...does MQX provide this?

Thanks!

Hello Wayne Hawthome,

file mqx.h has section TASK ERROR CODES where are error codes which are used by Kernel. I'll share at least the start of those:

#define MQX_INVALID_POINTER	(MQX_ERROR_BASE\|0x01)
#define MQX_INVALID_SIZE	(MQX_ERROR_BASE\|0x02)
#define MQX_NOT_RESOURCE_OWNER	(MQX_ERROR_BASE\|0x03)

This header file is located at mqx/source/include

Regards,

MartinK
