PTHREAD_CONDATTR(3) BSD Library Functions Manual PTHREAD_CONDATTR(3)NAME
pthread_condattr_destroy, pthread_condattr_init -- condition attribute operations
SYNOPSIS
#include <pthread.h>
int
pthread_condattr_destroy(pthread_condattr_t *attr);
int
pthread_condattr_init(pthread_condattr_t *attr);
DESCRIPTION
Condition attribute objects are used to specify parameters to pthread_cond_init(). FreeBSD's implementation of conditions does not support
any non-default attributes, so these functions are not very useful, though they are required to to be present by POSIX.
The pthread_condattr_init() function initializes a condition attribute object with the default attributes.
The pthread_condattr_destroy() function destroys a condition attribute object.
RETURN VALUES
If successful, these functions return 0. Otherwise, an error number is returned to indicate the error.
ERRORS
pthread_condattr_destroy() will fail if:
[EINVAL] Invalid value for attr.
pthread_condattr_init() will fail if:
[ENOMEM] Out of memory.

pthread_condattr_init() and pthread_condattr_destroy() conform to ISO/IEC 9945-1:1996 (``POSIX.1'')

pthread_condattr_init, pthread_condattr_destroy - condition creation attributes
SYNOPSIS
#include <pthread.h>
int pthread_condattr_init(pthread_condattr_t *attr);
int pthread_condattr_destroy(pthread_condattr_t *attr);
DESCRIPTION
Condition attributes can be specified at condition creation time, by passing a condition attribute object as second argument to
pthread_cond_init(3). Passing NULL is equivalent to passing a condition attribute object with all attributes set to their default values.
The LinuxThreads implementation supports no attributes for conditions. The functions on condition attributes are included only for compli-
ance with the POSIX standard.
pthread_condattr_init initializes the condition attribute object attr and fills it with default values for the attributes. pthread_con-
dattr_destroy destroys a condition attribute object, which must not be reused until it is reinitialized. Both functions do nothing in the
LinuxThreads implementation.
RETURN VALUE
pthread_condattr_init and pthread_condattr_destroy always return 0.

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.

Greetings,
I'm trying to delete a file with a weird name from within Terminal on a Mac.
It's a very old file (1992) with null characters in the name: ââWord FinderÂŽ Plusâ˘.
Here are some examples of what I've tried:

Hi all...
Well guys and gals, I jumped in at the deep end and found things that PERL cannot do by default.
Many tricky terminal escape codes are not catered for so I had to create workarounds.
One thing I searched for was this:

Well, guys I saw a question about GOTO for Python.
So this gave me the inspiration to attempt a GOTO function for 'dash', (bash and ksh too).

This is purely a fun project to see if it is possible in PURE... (3 Replies)
