Name

intro − introduction to the ULTRIX DECthreads library, which contains routines that allow you to perform multithreaded operations. 

Syntax

#include <pthread.h>

cc [options] files −lcma [libraries]

Description

The DECthreads routines are based on Draft 4 of the IEEE standard for multithreaded programming, POSIX 1003.4a.  This interface reports errors by setting the global errno value and returning a −1. 

When you use the library routines in a C program, compile it with the -lcma option to include the libcma library.  For example:

% cc -o prog prog.c -lcma

The routines for the DECthreads library are located in the /usr/lib/libcma.a directory.

The following DECthreads header files are located in the /usr/include/dce directory:

cma.h
cma_config.h
cma_errno.h
exc_handling.h
cma_px.h
cma_sigwait.h
cma_stdio.h
cma_ux.h
cmalib_ctrlx.h
pthread.h
pthread_exc.h

There is a message file associated with the DECthreads routines.  It is located in: /usr/lib/nls/msg/en_US.88591/dcethd.cat.
