Macro Definition Documentation #define rte_errno RTE_PER_LCORE(_rte_errno) Error number value, stored per-thread, which can be queried after calls to certain functions to determine why those functions failed. Uses standard values from errno.h wherever possible, with a small number of additional possible values for RTE-specific conditions. Definition at line 29 of file rte_errno.h. #define __ELASTERROR 1000 Check if we have a defined value for the max system-defined errno values. if no max defined, start from 1000 to prevent overlap with standard values Definition at line 49 of file rte_errno.h. Enumeration Type Documentation anonymous enum Error types Enumerator RTE_MIN_ERRNO Start numbering above std errno vals E_RTE_SECONDARY Operation not allowed in secondary processes E_RTE_NO_CONFIG Missing rte_config RTE_MAX_ERRNO Max RTE error number Definition at line 53 of file rte_errno.h. Function Documentation RTE_DECLARE_PER_LCORE (int, _rte_errno) Per core error number. const char * rte_strerror (int errnum) Function which returns a printable string describing a particular error code. For non-RTE-specific error codes, this function returns the value from the libc strerror function. Parameters errnum The error number to be looked up - generally the value of rte_errno Returns A pointer to a thread-local string containing the text describing the error.
