different macros, one for each project. Therefore, now we have OPAL_DECLSPEC, ORTE_DECLSPEC and OMPI_DECLSPEC. Please use them based on the sub-project. This commit was SVN r11270.

/* This file provide the external interface to our base component
|
|
* module. Most of the components that depend on it, will use the
|
|
* retain_component() function to increase the reference count on a
|
|
* particular component (as opposed to the retain() function, which is
|
|
* internal to the opal/mca/base). But it's convenient to have all
|
|
* the functions exported from one header file rather than to separate
|
|
* retain_component() and retain() into two separate header files
|
|
* (i.e., have a separate header file just for retain()).
|
|
*
|
|
* Note that internal to opal/mca/base, <ltdl.h> will *always* be
|
|
* included before this file, and <ltdl.h> is not included anywhere
|
|
* else in the OMPI tree. So checking for the LTDL_H preprocessor
|
|
* macro is a good indicator as to whether this file is being included
|
|
* from an opal/mca/base source file or not. If we are, then we need
|
|
* already have a real definition of lt_dlhandle. If we are being
|
|
* included from elsewhere, then <ltdl.h> will not previously have
|
|
* been included, LTDL_H will not be defined, and we need a fake
|
|
* definition of lt_dlhandle (or we'll get compile errors). So just
|
|
* typedef it to (void*).
|
|
*
|
|
* One more case that this handles is the --disable-dlopen case. In
|
|
* that case, even in opal/mca/base, we *won't* be including <ltdl.h>.
|
|
* Hence, LTDL_H won't be defined, so we'll end up typedefing
|
|
* lt_dlhandle to (void *). "But why does that matter?" you ask, "If
|
|
* we configure with --disable-dlopen, then lt_dlhandle shouldn't be
|
|
* used anywhere." Incorrect, Grasshopper. A small number of places
|
|
* (like the retain() function) are still prototyped, but have 99% of
|
|
* their innards #if'ed out -- i.e., they just return
|
|
* OPAL_ERR_NOT_SUPPORTED. Why was it coded up this way? I'm not
|
|
* entirely sure -- there may be a reason (and that reason may just be
|
|
* conservative coding), but I'm not really too inspired to look into
|
|
* it any further at this point. :-)
