al_cstr(3) Library Functions Manual al_cstr(3) NAME al_cstr - Allegro 5 API SYNOPSIS #include <allegro5/allegro.h> const char *al_cstr(const ALLEGRO_USTR *us) DESCRIPTION Get a char * pointer to the data in a string. This pointer will only be valid while the ALLEGRO_USTR(3) object is not modified and not destroyed. The pointer may be passed to functions expecting C-style strings, with the following caveats: * ALLEGRO_USTRs are allowed to contain embedded NUL ('\0') bytes. That means al_ustr_size(u) and strlen(al_cstr(u)) may not agree. * An ALLEGRO_USTR may be created in such a way that it is not NUL termi- nated. A string which is dynamically allocated will always be NUL termi- nated, but a string which references the middle of another string or re- gion of memory will not be NUL terminated. * If the ALLEGRO_USTR references another string, the returned C string will point into the referenced string. Again, no NUL terminator will be added to the referenced string. SEE ALSO al_ustr_to_buffer(3), al_cstr_dup(3) Allegro reference manual al_cstr(3)
