/*
** File: anonfm.c
** Description: Test anonymous file map
**
** Synopsis: anonfm [options] [dirName]
**
** Options:
** -d enable debug mode
** -h display a help message
** -s <n> size of the anonymous memory map, in KBytes. default: 100KBytes.
** -C 1 Operate this process as ClientOne()
** -C 2 Operate this process as ClientTwo()
**
** anonfn.c contains two tests, corresponding to the two protocols for
** passing an anonymous file map to a child process.
**
** ServerOne()/ClientOne() tests the passing of "raw" file map; it uses
** PR_CreateProcess() [for portability of the test case] to create the
** child process, but does not use the PRProcessAttr structure for
** passing the file map data.
**
** ServerTwo()/ClientTwo() tests the passing of the file map using the
** PRProcessAttr structure.
