+.Sh NAME
+.Nm reallocf
+.Nd memory reallocation function
+.Sh LIBRARY
+.Lb libc
+.Sh SYNOPSIS
+.In stdlib.h
+.Ft void *
+.Fn reallocf "void *ptr" "size_t size"
+.Sh DESCRIPTION
+The
+.Fn reallocf
+function is identical to the
+.Fn realloc
+function, except that it
+will free the passed pointer when the requested memory cannot be allocated.
+This is a
+.Fx
+specific API designed to ease the problems with traditional coding styles
+for
+.Fn realloc
+causing memory leaks in libraries.
+.Sh RETURN VALUES
+The
+.Fn reallocf
+function returns a pointer, possibly identical to
+.Fa ptr ,
+to the allocated memory
+if successful; otherwise a
+.Dv NULL
+pointer is returned, and
+.Va errno
+is set to
+.Er ENOMEM
+if the error was the result of an allocation failure.
+The
+.Fn reallocf
+function deletes the original buffer when an error occurs.
+.Sh SEE ALSO
+.Xr realloc 3
+.Sh HISTORY
+The
+.Fn reallocf
+function first appeared in
+.Fx 3.0 .
