pthread_mutexattr_settype(3)
NAME
  pthread_mutexattr_settype - Specifies the mutex type attribute that is used
  when a mutex is created

SYNOPSIS
  #include <pthread.h>

  int pthread_mutexattr_settype(
	  pthread_mutexattr_t *attr,
	  int type );

LIBRARY
  DECthreads POSIX 1003.1c Library (libpthread.so)

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

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

PARAMETERS
  attr
      Mutex attributes object whose mutex type attribute is to be modified.

  type
      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:

  0   Successful completion.

  [EINVAL]
