#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

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.
errnum | The error number to be looked up - generally the value of rte_errno |
