pthread_mutexattr_gettype(3)
NAME
  pthread_mutexattr_gettype - Obtains the mutex type attribute in the
  specified mutex attributes object

SYNOPSIS
  #include <pthread.h>

  int pthread_mutexattr_gettype(
	  const 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 obtained.

  type
      Receives the value of the mutex type attribute. The type argument
      specifies 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:

  0   Successful completion.

  [EINVAL]
      The value specified by attr is invalid.

ERRORS
