Obtains the object name from the thread object for an existing
    thread.

1  –  C Binding

    #include <pthread.h>

    int
    pthread_getname_np (
             pthread_thread_t   thread,
             char   *name,
             size_t   len);

2  –  Arguments

 thread

    Thread object whose object name is to be obtained.

 name

    Location to store the obtained object name.

 len

    Length in bytes of buffer at the location specified by name.

3  –  Description

    This routine copies the object name from the thread object
    specified by the thread argument to the buffer at the location
    specified by the name argument. Before calling this routine, your
    program must allocate the buffer indicated by name.

    The object name is a C language string and provides an identifier
    that is meaningful to a person debugging a multithreaded
    application. The maximum number of characters in the object name
    is 31.

    If the specified thread object has not been previously set with
    an object name, this routine copies a C language null string into
    the buffer at location name.

4  –  Return Values

    If an error condition occurs, this routine returns an integer
    value indicating the type of error. Possible return values are as
    follows:

    Return      Description

    0           Successful completion.
    [ESRCH]     The thread specified by thread does not exist.
