- move files out of toplevel include/ and etc/, moving it into the
sub-projects
- rather than including config headers with <project>/include,
have them as <project>
- require all headers to be included with a project prefix, with
the exception of the config headers ({opal,orte,ompi}_config.h
mpi.h, and mpif.h)

* Forks, execs, and waits for a subordinate program
|
|
*
|
|
* @param argv Null-terminated argument vector; argv[0] is the program
|
|
* (same as arguments to execvp())
|
|
*
|
|
* @param status Upon success, will be filled with the return status
|
|
* from waitpid(2). The WIF* macros can be used to examine the value
|
|
* (see waitpid(2)).
|
|
*
|
|
* @retval OPAL_SUCCESS If the child launched and exited.
|
|
* @retval OPAL_ERR_IN_ERRNO If a failure occurred, errno should be
|
|
* examined for the specific error.
|
|
*
|
|
* This function forks, execs, and waits for an executable to
|
|
* complete. The input argv must be a NULL-terminated array (perhaps
|
|
* built with the opal_arr_*() interface). Upon success, OPAL_SUCCESS
|
|
* is returned. This function will wait either until the child
|
|
* process has exited or waitpid() returns an error other than EINTR.
|
|
*
|
|
* Note that a return of OPAL_SUCCESS does \em not imply that the child
|
|
* process exited successfully -- it simply indicates that the child
|
|
* process exited. The WIF* macros (see waitpid(2)) should be used to
|
|
* examine the status to see hold the child exited.
|
|
*
|
|
* \warning This function should not be called if \c orte_init()
|
|
* or \c MPI_Init() have been called. This function is not
|
|
* safe in a multi-threaded environment in which a handler
|
|
* for \c SIGCHLD has been registered.
