Typedef Documentation

◆ mbcs_charlen_t

typedef qore_offset_t(* mbcs_charlen_t) (const char *str, qore_size_t valid_len)

for multi-byte encodings: gives the number of total bytes for the character given one or more characters

Parameters
stra pointer to the character data to check
lenthe number of valid bytes at the start of the character pointer
Returns
0=invalid, positive = number of characters needed, negative numbers = number of additional bytes needed to perform the check
