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

       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

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.
