我正在尝试在我的代码上标记警告的方法,但我做了一些错误,无法理解在哪里 . 我的编译器给了我太多关于每次使用这个宏的警告:
#define MPL_ERROR_MESSAGE2(output, fmt, ...) fprintf(output, ("\n[ERROR][%s:%d( %s )]\n--- " fmt " ---\n\n"), __FILE__, __LINE__, __PRETTY_FUNCTION__, ##__VA_ARGS__);
#define MPL_ERROR_MESSAGE(fmt, ...) MPL_ERROR_MESSAGE2(stderr, fmt, ##__VA_ARGS__);
使用示例:
MPL_ERROR_MESSAGE("Test %d", 2);

编辑2:按要求,其中一个触发警告的地方:
inline long arrayIndex(MPL_Position& sMPLP_p)
{
long x, y, z;
x = MPL_ROUND_INT((d_delta*sMPLP_p.getX())/d_sizeX__);
y = MPL_ROUND_INT((d_delta*sMPLP_p.getY())/d_sizeY__);
z = MPL_ROUND_INT((d_delta*sMPLP_p.getZ())/d_sizeZ__);
if( (x>=0) && (x<n_sizeX__) && (y>=0) && (y<n_sizeY__) && (z>=0) && (z<n_sizeZ__) ){ //isValidPosition(...)
return( (x*n_sizeY__ + y)*n_sizeZ__ + z );
}
MPL_ERROR_MESSAGE("Invalid Position at (%l, %l, %l)", x, y, z);
MPL_GE_InvalidPosition(sMPLP_p);
return( -1 );
}
(n_size?__和d_size?__是类属性;不要试图理解......:P)

关于编辑中列出的警告:
这个
应该
你传递
long signed int
.signed int
的转换说明符是d
. 当使用长度修饰符l
传递long
前缀时 .而且,虽然无关,但请从马科斯删除尾随
;
.我发现了它们之间的区别
和
当没有参数使用时,比如
第一个导致
而第二个导致
哪个错了 . 该死的错了 . 并且不要编译,因为MPL_ERROR_MESSAGE2并不期望最后一个逗号 . 你知道为什么会这样吗?我应该发一个新问题吗?
