#define VL()   fprintf(stderr, "\033[38;5;%dm# pid=%d\t%s:%d :: %s()\033[0m\n", getpid()%212+19, getpid(), __FILE__, __LINE__, __func__);
 Prints the name of the file and function to stderr (and implicitly flushes the output buffer).
 
#define VLog(format,...)   fprintf(stderr, "\033[38;5;%dm# pid=%d\t%s:%d :: %s()\t" format "\033[0m\n", getpid()%212+19, getpid(), __FILE__, __LINE__, __func__, ##__VA_ARGS__);
 Prints the name of the file and function, and printf()-style format/arguments, to stderr (and implicitly flushes the output buffer).
 
#define VLogHeap(heapPointer)   VLog("%s = %p (registered at %s)", #heapPointer, heapPointer, VuoHeap_getDescription(heapPointer));
 Prints the name of the current file and function, and the address and description of the specified heapPointer, to stderr (and implicitly flushes the output buffer).
 
#define VLogCF(coreFoundationRef)   { CFStringRef d = CFCopyDescription(coreFoundationRef); CFIndex len = CFStringGetLength(d)+1; char *z = (char *)malloc(len); CFStringGetCString(d, z, len, kCFStringEncodingUTF8); VLog("%s = %s", #coreFoundationRef, z); free(z); CFRelease(d); }
 Prints the specified Core Foundation object.
 

Macro Definition Documentation

#define VL ( )    fprintf(stderr, "\033[38;5;%dm# pid=%d\t%s:%d :: %s()\033[0m\n", getpid()%212+19, getpid(), __FILE__, __LINE__, __func__);

Prints the name of the file and function to stderr (and implicitly flushes the output buffer).

Useful for debugging.

Example:
void nodeEvent()
{
VL();
}
#define VLog (   format,
  ... 
)    fprintf(stderr, "\033[38;5;%dm# pid=%d\t%s:%d :: %s()\t" format "\033[0m\n", getpid()%212+19, getpid(), __FILE__, __LINE__, __func__, ##__VA_ARGS__);

Prints the name of the file and function, and printf()-style format/arguments, to stderr (and implicitly flushes the output buffer).

Useful for debugging.

Example:
void nodeEvent(VuoInputData(VuoInteger, "42") number)
{
VLog("%d", number);
}
#define VLogCF (   coreFoundationRef)    { CFStringRef d = CFCopyDescription(coreFoundationRef); CFIndex len = CFStringGetLength(d)+1; char *z = (char *)malloc(len); CFStringGetCString(d, z, len, kCFStringEncodingUTF8); VLog("%s = %s", #coreFoundationRef, z); free(z); CFRelease(d); }

Prints the specified Core Foundation object.

#define VLogHeap (   heapPointer)    VLog("%s = %p (registered at %s)", #heapPointer, heapPointer, VuoHeap_getDescription(heapPointer));

Prints the name of the current file and function, and the address and description of the specified heapPointer, to stderr (and implicitly flushes the output buffer).

Useful for debugging.

Example:
{
VLogHeap(shader);
}
