These functions return the complex sine of @var{z}.
The mathematical definition of the complex sine is
-@ifinfo

@math{sin (z) = 1/(2*i) * (exp (z*i) - exp (-z*i))}.
-@end ifinfo
+@end ifnottex
@tex
$$\sin(z) = {1\over 2i} (e^{zi} - e^{-zi})$$
@end tex
These functions return the complex cosine of @var{z}.
The mathematical definition of the complex cosine is
-@ifinfo
+@ifnottex
@math{cos (z) = 1/2 * (exp (z*i) + exp (-z*i))}
-@end ifinfo
+@end ifnottex
@tex
$$\cos(z) = {1\over 2} (e^{zi} + e^{-zi})$$
@end tex
These functions return the complex tangent of @var{z}.
The mathematical definition of the complex tangent is
-@ifinfo
+@ifnottex
@math{tan (z) = -i * (exp (z*i) - exp (-z*i)) / (exp (z*i) + exp (-z*i))}

logarithms) raised to the power of @var{z}.
Mathematically, this corresponds to the value
-@ifinfo
+@ifnottex
@math{exp (z) = exp (creal (z)) * (cos (cimag (z)) + I * sin (cimag (z)))}
-@end ifinfo
+@end ifnottex
@tex
$$\exp(z) = e^z = e^{{\rm Re}\,z} (\cos ({\rm Im}\,z) + i \sin ({\rm Im}\,z))$$
@end tex
These functions return the natural logarithm of @var{z}.
Mathematically, this corresponds to the value
-@ifinfo
+@ifnottex
@math{log (z) = log (cabs (z)) + I * carg (z)}
-@end ifinfo
+@end ifnottex
@tex
$$\log(z) = \log |z| + i \arg z$$
@end tex
These functions return the base 10 logarithm of the complex value
@var{z}. Mathematically, this corresponds to the value
-@ifinfo
+@ifnottex
@math{log (z) = log10 (cabs (z)) + I * carg (z)}
-@end ifinfo
+@end ifnottex
@tex
$$\log_{10}(z) = \log_{10}|z| + i \arg z$$
@end tex
If the function fails the return value is @code{NULL}.

+The four functions described so far in this section all work on a state
+which is shared by all threads. The state is not directly accessible to
+the user and can only be modified by these functions. This makes it
+hard to deal with situations where each thread should have its own
+pseudo-random number generator.
+
+The GNU C library contains four additional functions which contain the
+state as an explicit parameter and therefore make it possible to handle
+thread-local PRNGs. Beside this there are no difference. In fact, the
+four functions already discussed are implemented internally using the
+following interfaces.
+
+The @file{stdlib.h} header contains a definition of the following type:
+
+@comment stdlib.h
+@comment GNU
+@deftp {Data Type} {struct random_data}
+
+Objects of type @code{struct random_data} contain the information
+necessary to represent the state of the PRNG. Although a complete
+definition of the type is present the type should be treated as opaque.
+@end deftp
+
+The functions modifying the state follow exactly the already described
+functions.
+
+@comment stdlib.h
+@comment GNU
+@deftypefun int random_r (struct random_data *restrict @var{buf}, int32_t *restrict @var{result})
+The @code{random_r} function behaves exactly like the @code{random}
+function except that it uses and modifies the state in the object
+pointed to by the first parameter instead of the global state.
+@end deftypefun
+
+@comment stdlib.h
+@comment GNU
+@deftypefun int srandom_r (unsigned int @var{seed}, struct random_data *@var{buf})
+The @code{srandom_r} function behaves exactly like the @code{srandom}
+function except that it uses and modifies the state in the object
+pointed to by the second parameter instead of the global state.
+@end deftypefun
+
+@comment stdlib.h
+@comment GNU
+@deftypefun int initstate_r (unsigned int @var{seed}, char *restrict @var{statebuf}, size_t @var{statelen}, struct random_data *restrict @var{buf})
+The @code{initstate_r} function behaves exactly like the @code{initstate}
+function except that it uses and modifies the state in the object
+pointed to by the fourth parameter instead of the global state.
+@end deftypefun
+
+@comment stdlib.h
+@comment GNU
+@deftypefun int setstate_r (char *restrict @var{statebuf}, struct random_data *restrict @var{buf})
+The @code{setstate_r} function behaves exactly like the @code{setstate}
+function except that it uses and modifies the state in the object
+pointed to by the first parameter instead of the global state.

The @code{get_phys_pages} function returns the total number of pages of

be multiplied by the page size.
