** 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.
