From 1e66df3ee301209f4a38df097d7cc5cb9b367a3f Mon Sep 17 00:00:00 2001 From: Jeremy Fitzhardinge Date: Tue, 17 Jul 2007 18:37:02 -0700 Subject: add kstrndup Add a kstrndup function, modelled on strndup. Like strndup this returns a string copied into its own allocated memory, but it copies no more than the specified number of bytes from the source. Remove private strndup() from irda code.

This is deliberately simple - it does no quote processing of any kind. [ Seems to me that this is something which is already being done in the kernel, but I couldn't find any other implementations, either to steal or replace. Keep an eye out. ] Signed-off-by: Jeremy Fitzhardinge Signed-off-by: Chris Wright Cc: Andrew Morton Cc: Randy Dunlap --- include/linux/string.h | 3 +++ 1 file changed, 3 insertions(+) (limited to 'include/linux/string.h') diff --git a/include/linux/string.h b/include/linux/string.h index ee5e9ccc4aae..836062b7582a 100644 --- a/include/linux/string.h +++ b/include/linux/string.h @@ -108,6 +108,9 @@ extern char *kstrdup(const char *s, gfp_t gfp); extern char *kstrndup(const char *s, size_t len, gfp_t gfp); extern void *kmemdup(const void *src, size_t len, gfp_t gfp); +extern char **argv_split(gfp_t gfp, const char *str, int *argcp); +extern void argv_free(char **argv); + #ifdef __cplusplus } #endif -- cgit v1.2.3
