Purpose

The csetnumeric linter ensures that the given data contains only digits.

Functional Description

◆ gs1_lint_csetnumeric()

GS1_SYNTAX_DICTIONARY_API gs1_lint_err_t gs1_lint_csetnumeric ( const char *const  data,
size_t *const  err_pos,
size_t *const  err_len 
)

Used to validate that an AI component conforms to N..99 syntax.

Note: The length of the component is validated by the framework that calls this function.

Parameters
[in]dataPointer to the null-terminated data to be linted. Must not be NULL.
[out]err_posTo facilitate error highlighting, the start position of the bad data is written to this pointer, if not NULL.
[out]err_lenThe length of the bad data is written to this pointer, if not NULL.
Returns
GS1_LINTER_OK if okay.
GS1_LINTER_NON_DIGIT_CHARACTER if the data contains a non-digit character.
