3801 *
|
|
|
3802 * It is possible to call vim_findfile_init() again to reinitialise your search
|
|
|
3803 * with some new parameters. Don't forget to pass your old search context to
|
|
|
3804 * it, so it can reuse it and especially reuse the list of already visited
|
|
|
3805 * directories. If you want to delete the list of already visited directories
|
|
|
3806 * simply call vim_findfile_free_visited().
|
|
|
3807 *
|
|
|
3808 * When you are done call vim_findfile_cleanup() to free the search context.

5811 * Usage: i = putenv (string)
|
|
|
5812 * int i;
|
|
|
5813 * char *string;
|
|
|
5814 *
|
|
|
5815 * where string is of the form <name>=<value>.
|
|
|
5816 * Putenv returns 0 normally, -1 on error (not enough core for malloc).
|
|
|
5817 *
|
|
|
5818 * Putenv may need to add a new name into the environment, or to
|
|
|
5819 * associate a value longer than the current value with a particular
|
|
|
5820 * name. So, to make life simpler, putenv() copies your entire
|
|
|
5821 * environment into the heap (i.e. malloc()) from the stack
|
|
|
5822 * (i.e. where it resides when your process is initiated) the first
|
|
|
5823 * time you call it.
|
|
|
5824 *
|
|
|
5825 * (history removed, not very interesting. See the "screen" sources.)
