NAME    [Toc]    [Back]

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

SYNOPSIS    [Toc]    [Back]

       #include <pthread.h>

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

LIBRARY    [Toc]    [Back]

       DECthreads POSIX 1003.1c Library (libpthread.so)

STANDARDS    [Toc]    [Back]

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

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

PARAMETERS    [Toc]    [Back]

       Mutex attributes object  whose  mutex  type  attribute  is
       obtained.  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    [Toc]    [Back]

       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    [Toc]    [Back]

       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    [Toc]    [Back]

       None
