RTE_DECLARE_PER_LCORE (int, _rte_errno)
const char * rte_strerror (int errnum)

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.

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

RTE_MIN_ERRNO

Start numbering above std errno vals

E_RTE_SECONDARY

Per core error number.

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.
