Functional Description

◆ gs1_lint_hyphen()

GS1_SYNTAX_DICTIONARY_API gs1_lint_err_t gs1_lint_hyphen ( const char *const  data,
size_t *const  err_pos,
size_t *const  err_len 
)

Used to validate that an AI component contains only hyphens.

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_NOT_HYPHEN if the data contains a non-hyphen character.
