|
|
+.SH DESCRIPTION
|
|
+The
|
|
+.BR getcwd ()
|
|
+function copies an absolute pathname of the
|
|
+current working directory to the array pointed to by
|
|
+.IR buf ,
|
|
+which is of length
|
|
+.IR size .
|
|
+.PP
|
|
+If the current absolute path name would require a buffer
|
|
+longer than
|
|
+.I size
|
|
+elements,
|
|
+.B -1
|
|
+is returned, and
|
|
+.I errno
|
|
+is
|
|
+set to
|
|
+.BR ERANGE ;
|
|
+an application should check for this error,
|
|
+and allocate a larger buffer if necessary.
|
|
+.PP
|
|
+If
|
|
+.I buf
|
|
+is NULL, the behaviour of
|
|
+.BR getcwd ()
|
|
+is undefined.
|
|
+
|
|
+.SH "RETURN VALUE"
|
|
+.B -1
|
|
+on failure (for example, if the current directory is not readable), with
|
|
+.I errno
|
|
+set accordingly, and the number of characters stored in
|
|
+.I buf
|
|
+on success. The contents of the array pointed to by
|
|
+.IR buf
|
|
+is undefined on error.
|
|
+.PP
|
|
+Note that this return value differs from the
|
|
+.BR getcwd (3)
|
|
+library function, which returns
|
|
+.B NULL
|
|
+on failure and the address of
|
|
+.I buf
|
|
+on success.
|
|
+
|
|
+.SH ERRORS
|
|
+.TP
|
|

|
|
+if user memory cannot be mapped

|
|
+.SH SYNOPSIS
|
|
+.BI "long sys_rt_sigqueueinfo(int " pid ", int " sig ", siginfo_t * " uinfo ");
|
|
+.SH DESCRIPTION
|
|
+.BR sys_rt_sigqueueinfo ()
|
|
+sends the signal specified in
|
|
+.I sig
|
|
+to the process whose PID is given in
|
|
+.IR pid .
|
|
+The null signal (0) can be used to check if a process with a given
|
|
+PID exists.
|
|
+.PP
|
|
+The
|
|
+.I uinfo
|
|
+argument is used to specify an accompanying item of data (either an integer
|
|
+or a pointer value) in the sigval part of the
|
|
+siginfo_t structure to be sent with the signal.
|
|
+
|
|
+If the receiving process has installed a handler for this signal using the
|
|
+.B SA_SIGINFO
|
|
+flag to
|
|
+.BR sigaction (2),
|
|
+then it can obtain this data via the
|
|
+.I si_value
|
|
+field of the
|
|
+.I siginfo_t
|
|
+structure passed as the second argument to the handler.
|
|
+Furthermore, the
|
|
+.I si_code
|
|
+field of that structure will be set to
|
|
+.BR SI_QUEUE .
|
|
+.SH "RETURN VALUE"
|
|
+On success,
|
|
+.BR sys_rt_sigqueueinfo ()
|
|
+returns 0, indicating that the signal was successfully
|
|
+queued to the receiving proces.
|
|
+Otherwise, one of the following errors is returned.
|
|
+.SH ERRORS
|
|
+.TP
|
|
+.B -EAGAIN
|
|
+The limit of signals which may be queued has been reached.
|
|
+.TP
|
|
+.B -EINVAL
|

|
|
+was invalid.
|
|

|
|
+.B -ESRCH
|
|
+No process has a PID matching

|
+.B -EPERM
|
|
+The process does not have permission to send the signal
|
|
+to the receiving process.
|

+.B -EFAULT
|

+memory error.
|
|
+.SH NOTES
|
|
+If this function results in the sending of a signal to the process
|
|
+that invoked it, and that signal was not blocked by the calling thread,
|
|
+and no other threads were willing to handle this signal (either by
|
|
+having it unblocked, or by waiting for it using
|
|
+.BR sigwait (3)),
|
|
+then at least some signal must be delivered to this thread before this
|

|
|
+rt_sigtimedwait \- synchronously wait for queued signals

|
|
+.BI "long rt_sigtimedwait(const sigset_t *" uthese ", siginfo_t *" uinfo ", "
|
|
+.BI "const struct timespec " uts ", size_t " sigsetsize ");"
|
|
+.SH DESCRIPTION
|
|
+.BR rt_sigtimedwait ()
|
|
+suspends execution of the calling process until one of the signals in
|
|
+.I uthese
|
|
+is delivered.
|
|
+(If one of the signals in
|
|
+.I uthese
|
|
+is already pending for the calling process,
|
|
+.BR rt_sigtimedwait()
|
|
+will return immediately with information about that signal.)
|
|
+
|
|
+.BR rt_sigtimedwait()
|
|
+removes the delivered signal from the calling process's list of pending
|
|
+signals and returns the signal number as its function result.
|
|
+If the
|
|
+.I uinfo
|
|
+argument is not
|
|
+.BR NULL ,
|
|
+then it returns a structure of type
|
|
+.I siginfo_t
|
|
+
|
|
+The argument
|
|
+.IR uts ,
|
|
+enables an upper bound to be placed on the time for which
|
|
+the process is suspended.
|
|
+This argument is of the following type:
|
|
+.sp
|
|
+.in +2n
|
|
+.nf
|
|
+struct timespec {
|
|
+ long tv_sec; /* seconds */
|
|
+ long tv_nsec; /* nanoseconds */
|
|
+}
|
|
+.fi
|
|
+.in -2n
|
|
+.sp
|
|
+If both fields of this structure are specified as 0, a poll is performed:
|
|
+.BR rt_sigtimedwait ()
|
|
+returns immediately, either with information about a signal that
|
|
+was pending for the caller, or with an error
|
|
+if none of the signals in
|
|
+.I uthese
|
|
+was pending.
|
|
+.SH "RETURN VALUE"
|
|
+On success,
|
|
+.BR rt_sigtimedwait ()
|
|
+returns a signal number (i.e., a value greater than zero).
|
|
+On failure, returns one of the values from the ERRORS section below.
|
|
+.SH ERRORS
|
|
+.TP
|
