dnl This macro figures out how to build C programs using POSIX threads.

dnl It sets the PTHREAD_LIBS output variable to the threads library and

dnl linker flags, and the PTHREAD_CFLAGS output variable to any special
|

dnl C compiler flags that are needed. (The user can also force certain
|
||||
dnl compiler flags/libs to be tested by setting these environment
|

dnl variables.)

dnl
|

dnl Also sets PTHREAD_CC to any special C compiler that is needed for

dnl multi-threaded programs (defaults to the value of CC otherwise).

dnl (This is necessary on AIX to use the special cc_r compiler alias.)
|

dnl
|

dnl NOTE: You are assumed to not only compile your program with these
|
||||
dnl flags, but also link it with them as well. e.g. you should link
|

dnl with $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS
|
||||
dnl $LIBS
|
||||
dnl
|
||||
dnl If you are only building threads programs, you may wish to use

dnl

dnl LIBS="$PTHREAD_LIBS $LIBS"
|

dnl CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
|

dnl CC="$PTHREAD_CC"
|
||||
dnl
|

dnl In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute
|

dnl constant has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to
|

dnl that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).

dnl ACTION-IF-FOUND is a list of shell commands to run if a threads
