Anonymous Shared Memory
in the first protocol, the job of passing the inheritable shared memory is done via helper-functions with pr_createprocess.
... first protocol server: fm = pr_openanonfilemap(dirname, size, filemapprot); addr = pr_memmap(fm); attr = pr_newprocessattr(); pr_processattrsetinheritablefilemap( attr, fm, shmname ); pr_createprocess(client); pr_destroyprocessattr(attr); ...
...started by server via pr_createprocess() fm = pr_getinheritedfilemap( shmname ); addr = pr_memmap(fm); ...

PR_ProcessAttrSetInheritableFileMap
prepare filemap for export to my children processes via pr_createprocess.
... syntax #include <prshma.h> nspr_api(prstatus) pr_processattrsetinheritablefilemap( prprocessattr *attr, prfilemap *fm, const char *shmname ); parameters the function has the following parameters: attr pointer to a prprocessattr structure used to pass data to pr_createprocess.
...a subsequent call to pr_createprocess makes the prfilemap importable by the child process.

PR_GetInheritedFileMap
imports a prfilemap previously exported by my parent process via pr_createprocess.
... description pr_getinheritedfilemap retrieves a prfilemap object exported from its parent process via pr_createprocess.

sslfnc.html
initializing multi-processing with a shared ssl server cache to start a multi-processing application, the initial parent process calls ssl_configmpserversidcache, and then creates child processes, by one of these methods: call fork and then exec (unix) call createprocess (win32) call pr_createprocess (both unix and win32) it is essential that the parent allow the child to inherit the file descriptors.
...for the child to inherit the parent's environment you must set a specific argument to createprocess or pr_createprocess.

PRProcessAttr
pass a pointer to a prprocessattr into pr_createprocess when you create a new process, specifying information such as standard input/output redirection and file descriptor inheritance.
