Function Documentation

void explain_buffer_errno_adjtime ( explain_string_buffer_t sb,
int  errnum,
const struct timeval *  delta,
struct timeval *  olddelta 
)

The explain_buffer_errno_adjtime function is used to obtain an explanation of an error returned by the adjtime(2) system call. The least the message will contain is the value of strerror(errnum), but usually it will do much better, and indicate the underlying cause in more detail.

Parameters:
sbThe string buffer to print the message into. If a suitable buffer is specified, this function is thread safe.
errnumThe error value to be decoded, usually obtained from the errno global variable just before this function is called. This is necessary if you need to call any code between the system call to be explained and this function, because many libc functions will alter the value of errno.
deltaThe original delta, exactly as passed to the adjtime(2) system call.
olddeltaThe original olddelta, exactly as passed to the adjtime(2) system call.
