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
