Hi,
I am creating a file in Unix using a shell script. The file is getting created in the Unix - ANSI format. My requirement is to convert it to the PC - ANSI format. Can anyone tell me how to do this?
Thanks,

I have been wondering what the difference between pthread_rwlock_lock and pthread_mutex_lock is. Both these routines acquire an exclusive rw lock on an enclosed region.
So I performed a simple experiment in which I execute both these routines multiple times in a loop. Here are the results:... (1 Reply)
Executive summary:
Code (posted below) cores in AIX 5.3, despite being compiled and run successfully on several other operating systems. Code is attempting to verify that pthread_mutex_lock can be successfully aborted by siglongjmp. I do not believe this is an unreasonable requirement.

Hi
Is there a way to get the program/script name or function name usng built ins.
Like in many languages arg holds the program name

I follow the description of wiki (Lamport's bakery algorithm - Wikipedia, the free encyclopedia), then implement that algorithm in C, but it doesn't work, Starving is still here, is the implementation worry?
Only print out:
Thread ID: 0 START!
Thread ID: 0 END!
Thread ID: 0 START!... (2 Replies)
I am looking to create some ksh93 extensions using the custom builtin feature.
I can successfully create a builtin function, load it using the builtin -f command and get an output. However, I want to get/set values of KSH variables from within my built-in.
For example, lets say I am creating... (2 Replies)
Why do shell builtins like echo and pwd have binaries in /bin? When I do which pwd, I get the one in /bin. that means that I am not using the builtin version? What determines which one gets used? Is the which command a definitive way to determine what is being run when I enter pwd? (16 Replies)
I have put some yellow color codes and works well.
I call the funstion using
print_usage(stderr, 0);
I would like to know if there is any way, to store the ansi color codes in variables and then call them inside fprintf.
Or have a format followed by the strings I want to output.

Not sure if this is the right forum but I have collated a listing of shell and bash builtins.
Builtins is a loose word and may include the '/bin' drawer/folder/directory but NOT any
others in the path list.
In the case of my Macbook Pro, OSX 10.7.5 the enabled internals is also listed...

ATOMIC_DEC(3) BSD Library Functions Manual ATOMIC_DEC(3)NAME
atomic_dec, atomic_dec_32, atomic_dec_uint, atomic_dec_ulong, atomic_dec_ptr, atomic_dec_64, atomic_dec_32_nv, atomic_dec_uint_nv,
atomic_dec_ulong_nv, atomic_dec_ptr_nv, atomic_dec_64_nv -- atomic decrement operations
SYNOPSIS
#include <sys/atomic.h>
void
atomic_dec_32(volatile uint32_t *ptr);
void
atomic_dec_uint(volatile unsigned int *ptr);
void
atomic_dec_ulong(volatile unsigned long *ptr);
void
atomic_dec_ptr(volatile void *ptr);
void
atomic_dec_64(volatile uint64_t *ptr);
uint32_t
atomic_dec_32_nv(volatile uint32_t *ptr);
unsigned int
atomic_dec_uint_nv(volatile unsigned int *ptr);
unsigned long
atomic_dec_ulong_nv(volatile unsigned long *ptr);
void *
atomic_dec_ptr_nv(volatile void *ptr);
uint64_t
atomic_dec_64_nv(volatile uint64_t *ptr);
DESCRIPTION
The atomic_dec family of functions decrement (by one) the variable referenced by ptr in an atomic fashion.
The *_nv() variants of these functions return the new value.
The 64-bit variants of these functions are available only on platforms that can support atomic 64-bit memory access. Applications can check
for the availability of 64-bit atomic memory operations by testing if the pre-processor macro __HAVE_ATOMIC64_OPS is defined.
SEE ALSO atomic_ops(3)HISTORY
The atomic_dec functions first appeared in NetBSD 5.0.
