Typedef Documentation typedef unsigned char rte_uuid_t[16] Struct describing a Universal Unique Identifier Definition at line 24 of file rte_uuid.h. Function Documentation bool rte_uuid_is_null (const rte_uuid_t uu) Test if UUID is all zeros. Parameters uu The uuid to check. Returns true if uuid is NULL value, false otherwise static void rte_uuid_copy (rte_uuid_t dst, const rte_uuid_t src) [inline], [static] Copy uuid. Parameters dst Destination uuid src Source uuid Definition at line 61 of file rte_uuid.h. int rte_uuid_compare (const rte_uuid_t a, const rte_uuid_t b) Compare two UUID's Parameters a A UUID to compare b A UUID to compare Returns returns an integer less than, equal to, or greater than zero if UUID a is is less than, equal, or greater than UUID b. int rte_uuid_parse (const char * in, rte_uuid_t uu) Extract UUID from string Parameters in Pointer to string of characters to convert uu Destination UUID Returns Returns 0 on success, and -1 if string is not a valid UUID. void rte_uuid_unparse (const rte_uuid_t uu, char * out, size_t len) Convert UUID to string Parameters uu UUID to format out Resulting string buffer len Sizeof the available string buffer Author Generated automatically by Doxygen for DPDK from the source code.
