dbgputstr - print logs to the serial console
#include <stdio.h>
void dbgputstr(char const* characters, size_t length);
dbgputstr is Serenity's generic kernel-supported logging facility. Currently, logging submitted to dbgputstr is directly printed to the serial console.
dbgputstr takes as arguments a pointer to a string to be written, and the length of that string.
Users should access logging functionality via the dbg/dbgln functions, which add additional process information to the log output.
The C library function does not propagate errors.
The system call itself can fail with the following errors:
EFAULT: Invalid or inaccessible string.No error is reported if the output cannot be written to a serial device.
If the return value is positive, this indicates the actual number of characters written, in case the provided string was null-terminated before the length was reached.
