strlen function

strlen will give you the length of a string, NOT including the '\0' terminator. It should not be confused with the sizeof operator which returns the size of a variable (that could hold a string).

Library:   string.h

Prototype: size_t strlen(const char *s);

Syntax:	   size_t size;
	   char string[20]="red dwarf";
           size = strlen(string);

Examples

mlxsw: spectrum: Separate bc and mc floods
Break the bm (broadcast-multicast) into two tables, one for broadcast (and link local multicast that behaves like bc) and one for unknown multicasts. Add a bool into mlxsw_sp_port named mc_flood that reflect the value this port should have in the mc flood table (currently, always 1); Signed-off-by: Nogah Frankel <nogahf@mellanox.com> Signed-off-by: Yotam Gigi <yotamg@mellanox.com> Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S.
