pthread_attr_getname_np(3)				     Library Functions Manual					pthread_attr_getname_np(3)

NAME

       pthread_attr_getname_np - Obtain the object name attribute in a thread attributes object.

LIBRARY

       DECthreads POSIX 1003.1c Library (libpthread.so)

SYNOPSIS

       #include <pthread.h>

       int   pthread_attr_getname_np(
			     const pthread_attr_t      *attr,
			     char		       *name,
			     size_t		       len,
			     void		       **mbz);

PARAMETERS

       Address of the thread attributes object whose object name attribute is to be obtained.  Location to store the obtained object name.  Length
       in bytes of buffer at the location specified by name.  Reserved for future use. The value must be zero (0).

DESCRIPTION

       This routine copies the object name attribute from the thread attributes object specified by attr to  the  buffer  at  the  location  name.
       Before  calling	this  routine,	your  program must allocate the buffer indicated by name. A new thread created using the thread attributes
       object is initialized with the object name that was set in that attributes object.

       The object name is a C language string and provides an identifier that is meaningful to a person debugging a DECthreads-based multithreaded
       application.  The maximum number of characters in the object name is 31.

       If  the	specified  thread  attributes object has not been previously set with an object name, this routine copies a C language null string
       into the buffer at location name.

       This routine contrasts with pthread_getname_np, which obtains the object name from the thread object for an existing thread.

RETURN VALUES

       If an error condition occurs, this routine returns an integer value indicating the type of error.  Possible return values are  as  follows:
       Successful completion.  The value specified by attr is invalid.

ERRORS

       None

pthread_condattr_getpshared(3)				     Library Functions Manual				    pthread_condattr_getpshared(3)

NAME

       pthread_condattr_getpshared - Obtain the process-shared attribute of a condition variable attributes object.

LIBRARY

       DECthreads POSIX 1003.1c Library (libpthread.so)

SYNOPSIS

       #include <pthread.h>

       int   pthread_condattr_getpshared(
			     const pthread_condattr_t	  attr,
			     int			  *pshared);

PARAMETERS

       Address	of  the condition variable attributes object whose process-shared attribute is to be obtained.	Location to store the value of the
       process-shared attribute of attr.

DESCRIPTION

       This routine obtains the value of the process-shared attribute in the condition variable attributes object referenced by attr and stores it
       at the location pshared. The object referenced by attr must be initialized before this routine is called.

       Creating a condition variable whose process-shared attribute is set to PTHREAD_PROCESS_PRIVATE permits it to be operated on by threads cre-
       ated within the same process as the thread that initialized that condition variable.  If threads other than processes attempt to operate on
       such a condition variable, the behavior is undefined.

       The default value of the process-shared attribute of an initialized condition variable attributes object is PTHREAD_PROCESS_PRIVATE.

       Creating  a condition variable whose process-shared attribute is set to PTHREAD_PROCESS_SHARED permits it to be operated upon by any thread
       that has access to the memory where that condition variable is allocated, even if it is allocated in memory that is shared by multiple pro-
       cesses.

RETURN VALUES

       If  an  error condition occurs, this routine returns an integer value indicating the type of error.  Possible return values are as follows:
       Successful completion.  The value specified by attr is not a valid attributes object.

ERRORS

       None
