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

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.
