Typedef Documentation

typedef qore_size_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:

str	a pointer to the character data to check
len	the 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
