gethz(S-osr5)
gethz --
return the frequency of the system clock in ticks per second
Syntax
cc . . . -lc
int gethz()
Description
gethz
returns the frequency of the system clock in
ticks per second.
Warning
In the current implementation,
gethz
searches the environment list
(see
environ(M))
for a string of the form
HZ=val, and returns val.
If HZ cannot be interpreted as an integer,
gethz returns 0.
If HZ
is not defined in the environment,
gethz makes a call to
sysconf(S-osr5)
with parameter _SC_CLK_TCK
to determine the value of CLK_TCK.
gethz returns the value of CLK_TCK.
Note
The implementation of gethz may change.
