Detailed Description

API for error cause tracking

Definition in file rte_errno.h .

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

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.
