83  *
84  * mbed_error_status_t type represents the error status values under MbedOS. mbed_error_status_t values are signed integers and always be negative.\n
85  * Internally its encoded as below with bit-fields representing error type, module and error code:\n\n
86  * mbed_error_status_t Status Encoding:\n
87  *
88  \verbatim
89  | 31 Always Negative | 30-29(2 bits) | 28-24 | 23-16(8 bits) | 15-0(16 bits) |
90  | -1 | TYPE | (unused/reserved) | MODULE TYPE | ERROR CODE |
91  \endverbatim
92  *
93  * The error status value range for each error type is as follows:\n
94  * POSIX Error Status-es - 0xFFFFFFFF to 0xFFFFFF01(-1 -255) - This corresponds to POSIX error codes represented as negative.\n
95  * System Error Status-es - 0x80XX0100 to 0x80XX0FFF - This corresponds to System error codes range(all values are negative). Bits 23-16 will be module type(marked with XX)\n
96  * Custom Error Status-es - 0xA0XX1000 to 0xA0XXFFFF - This corresponds to Custom error codes range(all values are negative). Bits 23-16 will be module type(marked with XX)\n\n
97  *
98  * The ERROR CODE(values encoded into ERROR CODE bit-field in mbed_error_status_t) value range for each error type is also separated as below:\n
99  * POSIX Error Codes - 1 to 255.\n
100  * System Error Codes - 256 to 4095.\n
101  * Custom Error Codes - 4096 to 65535.\n
102  *
103  * @note POSIX error codes are always encoded as negative of their actual value. For example, EPERM is encoded as -EPERM.
104  * And, the MODULE TYPE for POSIX error codes are always encoded as MBED_MODULE_UNKNOWN.\n
105  * This is to enable easy injection of POSIX error codes into MbedOS error handling system without altering the actual POSIX error values.\n
106  * Accordingly, POSIX error codes are represented as -1 to -255 under MbedOS error status representation.

549  * Custom Error codes can be defined using the macro DEFINE_CUSTOM_ERROR\n
550  * This is mainly meant to capture non-generic error codes specific to a device.
551  * For example DEFINE_CUSTOM_ERROR( MY_CUSTOM_ERROR ,1 ) macro defines the following values:\n
552  * ERROR_CODE_MY_CUSTOM_ERROR = MBED_CUSTOM_ERROR_BASE+1\n
553  * ERROR_MY_CUSTOM_ERROR = MAKE_MBED_ERROR(ERROR_TYPE_CUSTOM, MBED_MODULE_UNKNOWN, ERROR_CODE_MY_CUSTOM_ERROR)\n

556  * ERROR_MY_CUSTOM_ERROR = 0xA0FF1001\n (Note that MODULE field is set to MBED_MODULE_UNKNOWN) \n\n
557  *
558  * @note
559  * **Using error codes:** \n
560  * POSIX error codes may be used in modules/functions currently using POSIX error codes and switching them to Mbed-OS error codes
561  * may cause interoperability issues. For example, some of the filesystem, network stack implementations may need to use
562  * POSIX error codes in order to keep them compatible with other modules interfacing with them, and may continue to use POSIX error codes.
563  *
564  * In all other cases, like for any native development of Mbed-OS modules Mbed-OS error codes should be used.
565  * This makes it easy to use Mbed-OS error reporting/logging infrastructure and makes debugging error scenarios
566  * much more efficient.
567  *
568  * @note
569  * **Searching for error codes in mbed-os source tree:** \n
570  * If you get an error report as below which you want to search for in mbed-os source tree, first take note of "Error Code" number. \n
571  * For example, the below error report has an error code of \b 259. Find the error name associated with the error code and in this case its \b INVALID_FORMAT. \n
572  * Use that error name(\b INVALID_FORMAT) to search the source tree for code locations setting that specific error code. \n
573  * If the Error module reported is not 255(which indicates unknown module), you can also use that to narrow down to the specific component reporting the error.
574  * See mbed_module_type_t enum above for module mapping. \n
