看是看了,可在建section那一章我被他给出的例子搞得一头雾水:
 roError ProDemoSectCreate(
double width,
double height,
double bite_radius,
double bite_height,
 roUtilCname name,
 roBoolean alloc,
 roSection *p_section)
{...........................................
return (-1); ::?::?
.............................................
.............................................
return(0); ::?::?
}
套用该例子时编译器提示需要显式类型转换,我实在不知该如何操作! |
