Function Documentation

void explain_buffer_errno_nanosleep ( explain_string_buffer_t sb,
int  errnum,
const struct timespec *  req,
struct timespec *  rem 
)

The explain_buffer_errno_nanosleep function is used to obtain an explanation of an error returned by the nanosleep(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.
reqThe original req, exactly as passed to the nanosleep(2) system call.
remThe original rem, exactly as passed to the nanosleep(2) system call.

void explain_buffer_errno_nanosleep_explanation ( explain_string_buffer_t sb,
int  errnum,
const char *  syscall_name,
const struct timespec *  req,
struct timespec *  rem 
)

The explain_buffer_errno_nanosleep_explanation function is used to obtain the explanation (the part after "because") of an error returned by the nanosleep(2) system call (and similar).

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.
syscall_nameThe name of the offending system call.
reqThe original req, exactly as passed to the nanosleep(2) system call.
remThe original rem, exactly as passed to the nanosleep(2) system call.
