pthread_mutexattr_settype(3)				     Library Functions Manual				      pthread_mutexattr_settype(3)

NAME

       pthread_mutexattr_settype - Specifies the mutex type attribute that is used when a mutex is created.

LIBRARY

       DECthreads POSIX 1003.1c Library (libpthread.so)

SYNOPSIS

       #include <pthread.h>

       int   pthread_mutexattr_settype(
			      pthread_mutexattr_t   *attr,
			      int		    type);

STANDARDS

       Interfaces documented on this reference page conform to industry standards as follows:

       IEEE Std 1003.1c-1995, POSIX System Application Program Interface

PARAMETERS

       Mutex attributes object whose mutex type attribute is to be modified.  New value for the mutex type attribute.  The type argument specifies
       the type of mutex that will be created.	Valid values are:  PTHREAD_MUTEX_NORMAL  PTHREAD_MUTEX_DEFAULT	(default)  PTHREAD_MUTEX_RECURSIVE
       PTHREAD_MUTEX_ERRORCHECK

DESCRIPTION

       This  routine  sets  the  mutex	type  attribute  that  is  used  to determine which type of mutex is created based on a subsequent call to
       pthread_mutex_init(3).

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 for attr or type is invalid.  The value specified by attr does not refer to an existing mutex
       attributes object.

ERRORS

       None

pthread_mutexattr_gettype(3)				     Library Functions Manual				      pthread_mutexattr_gettype(3)

NAME

       pthread_mutexattr_gettype - Obtains the mutex type attribute in the specified mutex attributes object.

LIBRARY

       DECthreads POSIX 1003.1c Library (libpthread.so)

SYNOPSIS

       #include <pthread.h>

       int   pthread_mutexattr_gettype(
			   const pthread_mutexattr_t   *attr,
			   int			       *type);

STANDARDS

       Interfaces documented on this reference page conform to industry standards as follows:

       IEEE Std 1003.1c-1995, POSIX System Application Program Interface

PARAMETERS

       Mutex  attributes object whose mutex type attribute is obtained.  Receives the value of the mutex type attribute.  The type argument speci-
       fies the type of mutex that is created.	Valid values are:  PTHREAD_MUTEX_NORMAL  PTHREAD_MUTEX_DEFAULT	(default)  PTHREAD_MUTEX_RECURSIVE
       PTHREAD_MUTEX_ERRORCHECK

DESCRIPTION

       This  routine  obtains the value of the mutex type attribute in the mutex attributes object specified by the attr argument and stores it in
       the location specified by the type argument.  See the pthread_mutexattr_settype(3) routine description for  information	about  mutex  type
       attributes.

RETURN VALUES

       On successful completion, this routine returns the mutex type in the location by the type argument.

       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
