Functional Description

gs1_lint_iso5218()

GS1_SYNTAX_DICTIONARY_API gs1_lint_err_t gs1_lint_iso5218	(	const char *const	data,
		size_t *const	err_pos,
		size_t *const	err_len
	)

Used to validate that an AI component is the string "0", "1", "2" or "9".

Parameters

[in]	data	Pointer to the null-terminated data to be linted. Must not be NULL.
[out]	err_pos	To facilitate error highlighting, the start position of the bad data is written to this pointer, if not NULL.
[out]	err_len	The length of the bad data is written to this pointer, if not NULL.

Returns

GS1_LINTER_OK if okay.

GS1_LINTER_INVALID_BIOLOGICAL_SEX_CODE if the data is not "0", "1", "2" or "9".
