52 * Error number value, stored per-thread, which can be queried after
53 * calls to certain functions to determine why those functions failed.
55 * Uses standard values from errno.h wherever possible, with a small number
56 * of additional possible values for RTE-specific conditions.
58 #define rte_errno RTE_PER_LCORE(_rte_errno)
61 * Function which returns a printable string describing a particular
62 * error code. For non-RTE-specific error codes, this function returns
63 * the value from the libc strerror function.
66 * The error number to be looked up - generally the value of rte_errno
68 * A pointer to a thread-local string containing the text describing
71 const char *rte_strerror(int errnum);
75 * Check if we have a defined value for the max system-defined errno values.
76 * if no max defined, start from 1000 to prevent overlap with standard values
