Get component value of RGBA color.

#define FXASSERT ( exp ) ((exp)?((void)0):(void)FX::fxassert(#exp,__FILE__,__LINE__))

FXASSERT() prints out a message when the expression fails, and nothing otherwise.
Unlike assert(), FXASSERT() will not terminate the execution of the application. When compiling your application for release, all assertions are compiled out; thus there is no impact on execution speed.

#define FXTRACE ( arguments ) FX::fxtrace arguments

FXTRACE() allows you to trace the execution of your application with increasing levels of detail the higher the trace level.
The trace level is determined by variable fxTraceLevel, which may be set from the command line with "-tracelevel <level>". When compiling your application for release, all trace statements are compiled out, just like FXASSERT. A statement like: FXTRACE((10,"The value of x=%d\n",x)) will generate output only if fxTraceLevel is set to 11 or greater. The default value fxTraceLevel=0 will block all trace outputs. Note the double parentheses!

#define FXMALLOC ( ptr,
type,
no ) (FX::fxmalloc((void **)(ptr),sizeof(type)*(no)))

Allocate a memory block of no elements of type and store a pointer to it into the address pointed to by ptr.
Return FALSE if size!=0 and allocation fails, TRUE otherwise. An allocation of a zero size block returns a NULL pointer.

#define FXCALLOC ( ptr,
type,
no ) (FX::fxcalloc((void **)(ptr),sizeof(type)*(no)))

Allocate a zero-filled memory block no elements of type and store a pointer to it into the address pointed to by ptr.
Return FALSE if size!=0 and allocation fails, TRUE otherwise. An allocation of a zero size block returns a NULL pointer.

#define FXRESIZE ( ptr,
type,
no ) (FX::fxresize((void **)(ptr),sizeof(type)*(no)))

Resize the memory block referred to by the pointer at the address ptr, to a hold no elements of type.
Returns FALSE if size!=0 and reallocation fails, TRUE otherwise. If reallocation fails, pointer is left to point to old block; a reallocation to a zero size block has the effect of freeing it. The ptr argument must be the address where the pointer to the allocated block is to be stored.

#define FXMEMDUP ( ptr,
src,
type,
no ) (FX::fxmemdup((void **)(ptr),(const void*)(src),sizeof(type)*(no)))

Allocate and initialize memory from another block.
Return FALSE if size!=0 and source!=NULL and allocation fails, TRUE otherwise. An allocation of a zero size block returns a NULL pointer. The ptr argument must be the address where the pointer to the allocated block is to be stored.

#define FXFREE ( ptr ) (FX::fxfree((void **)(ptr)))

Free a block of memory allocated with either FXMALLOC, FXCALLOC, FXRESIZE, or FXMEMDUP.
It is OK to call free a NULL pointer. The argument must be the address of the pointer to the block to be released. The pointer is set to NULL to prevent any further references to the block after releasing it.

#define fabsf ( x ) ((float)fabs((double)(x)))

These are some of the ISO C99 standard single-precision transcendental functions.
On LINUX, specify _GNU_SOURCE or _ISOC99_SOURCE to enable native implementation; otherwise, these macros will be used. Apple OS-X implements fabsf(x), ceilf(x), floorf(x), and fmodf(x,y). Define FLOAT_MATH_FUNCTIONS if these functions are available in some other library you're linking to.

#define ceilf ( x ) ((float)ceil((double)(x)))

#define floorf ( x ) ((float)floor((double)(x)))

#define fmodf ( x,
y ) ((float)fmod((double)(x),(double)(y)))

#define sqrtf ( x ) ((float)sqrt((double)(x)))
