NAMEuconvert_size - Number of bytes needed to store a string after conversion. Allegro game programming library.
DESCRIPTIONFinds out how many bytes are required to store the specified string `s' after a conversion from `type' to `newtype', including the mandatory zero terminator of the string. You can use U_CURRENT for either `type' or `newtype' as a shortcut to represent whatever text encoding format is currently selected. Example:
length = uconvert_size(old_string, U_CURRENT, U_UNICODE); new_string = malloc(length); ustrcpy(new_string, old_string);
