Error code layout.

Currently we try to keep all error codes within the negative space of 16 bits signed integers to support all platforms (-0x0001 - -0x7FFF). In addition we'd like to give two layers of information on the error if possible.

For that purpose the error codes are segmented in the following manner:

16 bit error code bit-segmentation

1 bit - Unused (sign bit) 3 bits - High level module ID 5 bits - Module-dependent error code 7 bits - Low level module errors

For historical reasons, low-level error codes are divided in even and odd, even codes were assigned first, and -1 is reserved for other errors.

#define MBEDTLS_ERROR_ADD	(	high,

	)	mbedtls_error_add( high, low, __FILE__, __LINE__ )

Combines a high-level and low-level error code together.

Wrapper macro for mbedtls_error_add(). See that function for more details.

Definition at line 127 of file error.h.

Function Documentation

static int mbedtls_error_add	(	int	high,
		int	low,
		const char *	file,
		int	line
	)

inlinestatic

Combines a high-level and low-level error code together.

This function can be called directly however it is usually called via the MBEDTLS_ERROR_ADD macro.

While a value of zero is not a negative error code, it is still an error code (that denotes success) and can be combined with both a negative error code or another value of zero.

Note: When invasive testing is enabled via MBEDTLS_TEST_HOOKS, also try to call mbedtls_test_hook_error_add.

Parameters

high	high-level error code. See error.h for more details.
low	low-level error code. See error.h for more details.
file	file where this error code addition occurred.
line	line where this error code addition occurred.

Definition at line 156 of file error.h.

const char* mbedtls_high_level_strerr ( int error_code )

Translate the high-level part of an Mbed TLS error code into a string representation.

This function returns a const pointer to an un-modifiable string. The caller must not try to modify the string. It is intended to be used mostly for logging purposes.

Parameters

error_code error code

Returns: The string representation of the error code, or NULL if the error code is unknown.

const char* mbedtls_low_level_strerr ( int error_code )

Translate the low-level part of an Mbed TLS error code into a string representation.

This function returns a const pointer to an un-modifiable string. The caller must not try to modify the string. It is intended to be used mostly for logging purposes.

Parameters

error_code error code

Returns: The string representation of the error code, or NULL if the error code is unknown.

void mbedtls_strerror	(	int	errnum,
		char *	buffer,
		size_t	buflen
	)

Translate a mbed TLS error code into a string representation, Result is truncated if necessary and always includes a terminating null byte.

Parameters

errnum	error code
buffer	buffer to place representation in
buflen	length of the buffer

Variable Documentation

void(* mbedtls_test_hook_error_add)(int, int, const char *, int)

Testing hook called before adding/combining two error codes together. Only used when invasive testing is enabled via MBEDTLS_TEST_HOOKS.
