NAME

       PMIx_Init - Initialize the PMIx Client

SYNOPSIS

              #include <pmix.h>

              pmix\_status\_t PMIx_Init(pmix\_proc\_t *proc);

ARGUMENTS

       proc : Pointer to a pmix_proc_t object in which the client's namespace and rank are to be returned.

DESCRIPTION

       Initialize the PMIx client, returning the process identifier assigned to this client's application in the
       provided pmix_proc_t struct.  Passing a value of NULL for this parameter is allowed if  the  user  wishes
       solely to initialize the PMIx system and does not require return of the identifier at that time.

       When  called, the PMIx client will check for the required connection information of the local PMIx server
       and will establish the connection.  If the information is not found, or the server connection fails, then
       an appropriate error constant will be returned.

       If  successful,  the  function  will  return  PMIX_SUCCESS  and will fill the provided structure with the
       server-assigned namespace and rank of the process within  the  application.   In  addition,  all  startup
       information  provided by the resource manager will be made available to the client process via subsequent
       calls to PMIx_Get.

       Note that the PMIx client library is referenced counted, and so multiple calls to PMIx_Init are  allowed.
       Thus, one way to obtain the namespace and rank of the process is to simply call PMIx_Init with a non-NULL
       parameter.

RETURN VALUE

       Returns PMIX_SUCCESS on success.  On error, a negative value corresponding to a PMIx errno is returned.

ERRORS

       PMIx errno values are defined in pmix_common.h.
