+ *
+ * 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
+ * Internally its encoded as below with bit-fields representing error type, module and error code:\n\n
+ * mbed_error_status_t Status Encoding:\n
+ *
+ \verbatim
+ | 31 Always Negative | 30-29(2 bits) | 28-24 | 23-16(8 bits) | 15-0(16 bits) |
+ | -1 | TYPE | (unused/reserved) | MODULE TYPE | ERROR CODE |
+ \endverbatim
+ *
+ * The error status value range for each error type is as follows:\n
+ * Posix Error Status-es - 0xFFFFFFFF to 0xFFFFFF01(-1 -255) - This corresponds to Posix error codes represented as negative.\n
+ * 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
+ * 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
+ *
+ * The ERROR CODE(values encoded into ERROR CODE bit-field in mbed_error_status_t) value range for each error type is also seperated as below:\n
+ * Posix Error Codes - 1 to 255.\n
+ * System Error Codes - 256 to 4095.\n
+ * Custom Error Codes - 4096 to 65535.\n
+ *
+ * @note Posix error codes are always encoded as negative of their actual value. For example, EPERM is encoded as -EPERM.
+ * And, the MODULE TYPE for Posix error codes are always encoded as MBED_MODULE_UNKNOWN.\n
+ * This is to enable easy injection of Posix error codes into MbedOS error handling system without altering the actual Posix error values.\n
+ * Accordingly, Posix error codes are represented as -1 to -255 under MbedOS error status representation.

+ * @note
+ * Custom Error codes can be defined using the macro DEFINE_CUSTOM_ERROR\n
+ * This is mainly meant to capture non-generic error codes specific to a device.
+ * For example DEFINE_CUSTOM_ERROR( MY_CUSTOM_ERROR ,1 ) macro defines the following values:\n
+ * ERROR_CODE_MY_CUSTOM_ERROR = MBED_CUSTOM_ERROR_BASE+1\n
+ * ERROR_MY_CUSTOM_ERROR = MAKE_MBED_ERROR(ERROR_TYPE_CUSTOM, MBED_MODULE_UNKNOWN, ERROR_CODE_MY_CUSTOM_ERROR)\n
+ * Its effectively equivalent to:\n
+ * ERROR_CODE_MY_CUSTOM_ERROR = 4097\n
+ * ERROR_MY_CUSTOM_ERROR = 0xA0FF1001\n (Note that MODULE field is set to MBED_MODULE_UNKNOWN) \n\n
+ *
+ * @note
+ * **Using error codes:** \n
+ * Posix error codes may be used in modules/functions currently using Posix error codes and switching them to Mbed-OS error codes
+ * may cause interoperability issues. For example, some of the filesystem, network stack implementations may need to use
+ * Posix error codes in order to keep them compatible with other modules interfacing with them, and may continue to use Posix error codes.
+ *
+ * In all other cases, like for any native development of Mbed-OS modules Mbed-OS error codes should be used.
+ * This makes it easy to use Mbed-OS error reporting/logging infrastructure and makes debugging error scenarios
+ * much more efficient.
+ *
+ * @note
+ * **Searching for error codes in mbed-os source tree:** \n
+ * 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
+ * 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
+ * Use that error name(\b INVALID_FORMAT) to search the source tree for code locations setting that specific error code. \n
+ * 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.
+ * See mbed_module_type_t enum above for module mapping. \n
