NAME
call_usermodehelper_setup - prepare to call a usermode helper
SYNOPSIS
struct subprocess_info * call_usermodehelper_setup(char * path, char ** argv, char ** envp, gfp_t gfp_mask, int (*init) (struct subprocess_info *info, struct cred *new), void (*cleanup) (struct subprocess_info *info), void * data);
ARGUMENTS
path path to usermode executable argv arg vector for process envp environment for process gfp_mask gfp mask for memory allocation init an init function cleanup a cleanup function data arbitrary context sensitive data
DESCRIPTION
Returns either NULL on allocation failure, or a subprocess_info structure. This should be passed to call_usermodehelper_exec to exec the process and free the structure. The init function is used to customize the helper process prior to exec. A non-zero return code causes the process to error out, exit, and return the failure to the calling process The cleanup function is just before ethe subprocess_info is about to be freed. This can be used for freeing the argv and envp. The Function must be runnable in either a process context or the context in which call_usermodehelper_exec is called.
