Purpose

The yyyymmdd linter ensures that the data represents a meaningful date, in YYYYMMDD format.

Functional Description

gs1_lint_yyyymmdd()

GS1_SYNTAX_DICTIONARY_API gs1_lint_err_t gs1_lint_yyyymmdd	(	const char *const	data,
		size_t *const	err_pos,
		size_t *const	err_len
	)

Used to ensure that an AI component conforms to the YYYYMMDD format.

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_DATE_TOO_SHORT if the data is too short for YYYYMMDD format.

GS1_LINTER_DATE_TOO_LONG if the data is too long for YYYYMMDD format.

GS1_LINTER_NON_DIGIT_CHARACTER if the data contains a non-digit character.

GS1_LINTER_ILLEGAL_MONTH if the data contains an invalid month.

GS1_LINTER_ILLEGAL_DAY if the data contains an invalid day of the month.
