Detailed Description

RTEMS associativity routines. Mainly used to convert a value from one space to another (eg: our errno's to host errno's and vice-versa)

Function Documentation

rtems_assoc_32_to_string()

size_t rtems_assoc_32_to_string	(	uint32_t	value,
		char *	buffer,
		size_t	buffer_size,
		const rtems_assoc_32_pair *	pairs,
		size_t	pair_count,
		const char *	separator,
		const char *	fallback
	)

Converts the specified value into a text representation.

Parameters

[in]	value	The value to convert.
[in]	buffer	The buffer for the text representation.
[in]	buffer_size	The buffer size in characters.
[in]	pairs	Names for particular bits.
[in]	pair_count	Count of pairs.
[in]	separator	Separator between individual names.
[in]	fallback	Fallback value in case no bits contained in the pairs are set in the value.

Return values

The	length of the text representation. May be greater than or equal to the buffer size if truncation occurred.

rtems_assoc_thread_states_to_string()

size_t rtems_assoc_thread_states_to_string	(	uint32_t	states,
		char *	buffer,
		size_t	buffer_size
	)

Converts the specified thread states into a text representation.

Parameters

[in]	states	The thread states to convert.
[in]	buffer	The buffer for the text representation.
[in]	buffer_size	The buffer size in characters.

Return values

The	length of the text representation. May be greater than or equal to the buffer size if truncation occurred.
