NAME
pthread_attr_init(), pthread_attr_destroy() - initialize or destroy a thread attributes object
SYNOPSIS
PARAMETERS
attr Pointer to the thread attributes object to be initialized or destroyed.
DESCRIPTION
initializes a thread attributes object attr with the default value for all the thread attributes.
When a thread attributes object is used to create a thread, the values of the individual attributes determine the characteristics of the
new thread. Attributes objects act like additional parameters to object creation. A single attributes object can be used in multiple calls
to
After a thread attributes object has been used to initialize one or more threads, any function affecting the attributes object does not
affect the previously created threads.
The thread attributes and their default values are:
stacksize POSIX.1c does not define a default value. On HP-UX released on PA-RISC platforms, the default is 64K. On HP-UX
released on Itanium(R)-based platforms, the default is 256K.
guardsize The default value is bytes.
stackaddr The default value is NULL.
detachstate The default value is

destroys the thread attributes object attr. The destroyed thread attributes object ceases to exist and its resources are reclaimed. Refer-
encing the object after it has been destroyed results in undefined behavior. A destroyed thread attributes object can be reinitialized
using thread attribute initialization routine
Threads that have already been created using this attributes object are not affected by the destruction of the thread attributes object.
RETURN VALUE
Upon successful completion, and return zero. Otherwise, an error number is returned to indicate the error (the variable is not set).
ERRORS
If any of the following occur, the function returns the corresponding error number:
[ENOMEM] There is insufficient memory available in which to initialize the pthread attributes object.
[EINVAL] The value specified by attr is invalid.
If any of the following occur, the function returns the corresponding error number:
