Where can I find the implementation of "time.h"?

Question

Where can I find the implementation of time.h in the standard C library, i.e. time.c ?

I tried using Google Code Search time.c Is the implementation in the Linux kernel?

Answer 1

time.h is the header from the C standard library.

You will find implementations of the various functions that this header provides in the library implementation from your system. For example, the implementation of the difftime function in libc used for NetBSD can be found in src / lib / libc / time / difftime.c .

Answer 2

For GNU libc, see http://sourceware.org/git/?p=glibc.git;a=tree;f=time;h=c950c5d4dd90541e8f3c7e1649fcde4aead989bb;hb=master

Answer 3

You can find the implementation in the GNU libc library. There is more than one time.c. file Each function (in a first approximation) lives in its own compilation unit.

Answer 4

Are you really looking for a C implementation in the standard library? Each compiler and OS usually have their own implementation (only headers are relatively standard).

You can see instructions for downloading sources for GNU C here: http://www.gnu.org/software/libc/resources.html

Answer 5

time.h is the standard C header, so it describes the functions from the standard C library with which it came. For example, GNU libc
