Table 3-1 lists TP1/Client functions.

You can use dc_xxx_xxx_s functions and character code conversion functions in a multi-thread environment. If both function versions (dc_xxx_xxx_s and dc_xxx_xxx) are supported, except for character code conversion functions, use the dc_xxx_xxx_s version of functions.

Since not all functions have the dc_xxx_xxx_s version, see the Release Notes that came with the program product to check whether the functions you want to use have the dc_xxx_xxx_s version.

For details about each function, see 4. TP1/Client Functions (C Language).
