+.SH DESCRIPTION
+The
+.BR libsimple_reallocn (),
+.BR libsimple_enreallocn (),
+and
+.BR libsimple_ereallocn ()
+functions are wrappers for the
+.BR realloc (3)
+function, they reallocate memory allocated on
+the heap and return the older pointer ot a new
+pointer with the alignment of
+.I alignof(max_align_t)
+to the allocated memory of 
+.I N
+bytes, where
+.I N
+is the product of
+.I n
+and all following arguments (which should have the type
+.BR size_t )
+up to the first 0;
+.I n
+must not be 0. The returned pointer will contain the
+same content as
+.IR ptr ,
+but truncated to
+.I N
+bytes if it is smaller or with the new bytes
+unitialised if it is larger. If a new pointer
+is returned, rather than
+.IR ptr ,
+.I ptr
+is deallocated;
+.I ptr
+is not deallocated on failure. The function
+.BR free (3)
+shall be called with the returned pointer as
+input when the allocated memory is no longer needed.
+.PP
+The
+.BR libsimple_enreallocn ()
+and
+.BR libsimple_ereallocn ()
+functions will terminate the process if the memory
+cannot be allocated, by calling the
+.BR libsimple_enprintf ()
+and
+.BR libsimple_eprintf ()
+functions, respectively.
+On failure, the process's exit value will be
+.I status
+if the
+.BR libsimple_enreallocn ()
+function is used or
+.IR libsimple_default_failure_exit (3)
+if the
+.BR libsimple_ereallocn ()
+function is used.
+.PP
+The
+.BR libsimple_vreallocn (),
+.BR libsimple_envreallocn (),
+and
+.BR libsimple_evreallocn ()
+functions are versions of the
+.BR libsimple_reallocn (),
+.BR libsimple_enreallocn (),
+and
+.BR libsimple_ereallocn (),
+respectively, that use
+.B va_list
+instead of variadic arguments.
+.SH RETURN VALUE
+The
+.BR libsimple_vreallocn (),
+.BR libsimple_envreallocn (),
+.BR libsimple_evreallocn (),
+.BR libsimple_reallocn (),
+.BR libsimple_enreallocn (),
+and
+.BR libsimple_ereallocn ()
+functions return a pointer to the allocated memory
+upon success completion; otherwise the
+.BR libsimple_vreallocn ()
+and
+.BR libsimple_reallocn ()
+functions return
+.B NULL
+and set
+.I errno
+it indicate the error, and the
+.BR libsimple_envreallocn (),
+.BR libsimple_evreallocn (),
+.BR libsimple_enreallocn (),
+and
+.BR libsimple_ereallocn ()
+functions terminated the process.
+.SH ERRORS
+The
+.BR libsimple_vreallocn (),
+.BR libsimple_reallocn ()
+function will fail for the reasons specified for the
+.BR realloc (3)
+function, and if:
+.TP
+.B EINVAL
+.I n
+is 0.
+.PP
+The
+.BR libsimple_envreallocn (),
+.BR libsimple_evreallocn (),
+.BR libsimple_enreallocn (),
+and
+.BR libsimple_ereallocn ()
+functions will terminate the process on failure.
