Implement missing <search.h>, <stdio.h>, <stdlib.h>, <wchar.h> functions and definitions

[scottmc]

These are present in the search.h header, but not yet implemented, so you'll need to implement these:

search.h:

hcreate hdestroy hsearch

The following issues also need to be adressed in <search.h>, <stdio.h>, <stdlib.h> and <wchar.h> This list may or may not be complete and correct, so further research may be required, when in doubt, consult the opengroup spec. ​http://www.opengroup.org/onlinepubs/9699919799/basedefs/stdio.h.html ​http://www.opengroup.org/onlinepubs/9699919799/basedefs/stdlib.h.html ​http://www.opengroup.org/onlinepubs/9699919799/basedefs/search.h.html ​http://www.opengroup.org/onlinepubs/9699919799/basedefs/wchar.h.html

stdio.h

1. Cannot find the definition of FILE data type as explained at opengroup.org:

"A structure containing information about a file, defined through typedef."

There's also a few more that are POSIX required but missing in the headers and need to be implemented:

wchar.h

1. The tag "tm" is not declared as described at opengroup.org.

stdlib.h

1. "<sys/wait.h>" seems not to be included, so

"WNOHANG WUNTRACED WEXITSTATUS WIFEXITED WIFSIGNALED WIFSTOPPED WSTOPSIG WTERMSIG" definition is missing, (probably just need to #include <sys/wait.h>)

2. Definition/Declaration of "long a64l(const char *);" is missing.
3. Definition/Declaration of "int atexit(void (*)(void));" is missing.
4. Definition/Declaration of "div_t div(int, int);" is missing.
5. Definition/Declaration of "char* l64a(long);" is missing.

This has been posted as a GCI task: ​http://www.google-melange.com/gci/task/show/google/gci2010/haiku/t129139814475

The part on FILE is wrong. It's defined in stdio_pre.h which is included in stdio.h.

Adding a "struct tm;" covers the wchar.h part indeed.

[kaliber]

Implemented in hrev43470

[TriEdgeAI]

Implements a64l()

[TriEdgeAI]

Implements l64a()

[TriEdgeAI]

Suggests fixes on implementation of div(), ldiv(), lldiv()

[TriEdgeAI]

Adds a few missing lines to stdlib.h

[TriEdgeAI]

Adds a missing line in wchar.h

[TriEdgeAI]

The file I used to test the correctness of the implemented and the fixed functions.

Summary of work for Google Code-In task:

---

The hashtable functions were already implemented. Same goes for atexit(). div() was implemented, but was giving incorrect results, so I made a patch for it. a64l() and l64a() were not implemented, so I am providing both as standalone files. There are also patches for stdlib.h and wchar.h.

[scottmc]

Can someone check and apply these and then close this one out?

[korli]

Applied in hrev46161.

[korli]

Wrong bug....

[korli]

and assigning back :)

[luroh]

Move POSIX compatibility related tickets out of R1 milestone (FutureHaiku/Features).

[korli]

Applied patches with the help of Puck Meerburg in hrev48500.
