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.

Examples:
examples/ipsec-secgw/ipsec-secgw.c, examples/ipsec-secgw/sa.c, examples/packet_ordering/main.c, examples/quota_watermark/qw/init.c, and examples/quota_watermark/qw/main.c.

Definition at line 58 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 78 of file rte_errno.h.

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
errnumThe 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.
Examples:
examples/l2fwd-jobstats/main.c, examples/packet_ordering/main.c, examples/quota_watermark/qw/init.c, and examples/quota_watermark/qw/main.c.
