|
|
* RunFileCommand
|
|
* This function is called to fork a process and run a command in the
|
|
* event that PAM does not have the appropriate capabilities (i.e. PAM
|
|
* isn't superuser and superuser privilege is required). PAM waits
|
|
* for completion of the forked command process.
|
|
*
|
|
* PARAMETERS:
|
|
*
|
|
* command_path -- this is a pointer to the full pathname of the
|
|
* command to be run.
|
|
*
|
|
* argument1 -- this is a pointer to the first command argument.
|
|
*
|
|
* argument2 -- this is a pointer to the second command argument.
|
|
*
|
|
* argument3 -- this is a pointer to the third command argument.
|
|
*
|
|
* RETURN VALUE:
|
|
*
|
|
* If the command could not be run or if it exited with a non-zero
|
|
* value then a non-zero value is returned.
