I do everything in C++ with STL but I have to utilitize legacy C functions within my member functions (methods).
The legacy C function signature is...
extern int UF_DRF_create_label(
char text_string[ ][132+1] ,
double model_pos_3d[ 3 ],
tag_t * label_tag);
My issue is converting my std::vector<std::string> into the char text_string[132+1].
Please, some sample code ideals!!!
