File Descriptor Printf - fdprintf

Functions
int	fdprintf (int fc, const char *format,...)
	printf to a file descriptor
int	fdiprintf (int fc, const char *format,...)
	printf to a file descriptor with integer (no floating point) support
int	vfdprintf (int fc, const char *format, va_list arg)
	printf to a file descriptor using va_list arguments
int	vfdiprintf (int fc, const char *format, va_list arg)
	printf to a file descriptor with integer (no floating point) support using va_list arguments

Detailed Description

#include< fdprintf.h >

The printf() function is a valuable tool for messages at runtime, status, and debugging. The fdprintf() uses the same parameters, but is used to printf to any file descriptor, such as serial ports, network interfaces, and custom file descriptors.

Note

Please refer to the fdprintf() example in the "\nburn\examples\Filedescriptor" folder. There are also examples on how to create a custom file descriptor.
