◆ err_msg
| char* err_msg[] |
Initial value:
= {
"VOLK_ERROR: Runtime error.",
"VOLK_PARSE_ERR: Error parsing input.",
"VOLK_VALUE_ERR: Invalid input.",
"VOLK_TXN_ERR: MDB transaction error.",
"VOLK_DB_ERR: Database error.",
"VOLK_NOT_IMPL_ERR: Feature is not implemented.",
"VOLK_IO_ERR: Input/Output error.",
"VOLK_MEM_ERR: Memory error.",
"VOLK_CONFLICT_ERR: A resource conflict interrupted the operation.",
"VOLK_ENV_ERR: Environment not initialized. Did you call VOLK_init()?",
}
error messages.
Note that all error values are < 0 so it is possible to set conditions to be triggered only by error return values.
The message corresponding to the rc is found by err_msg[rc - VOLK_MIN_ERROR]. VOLK_strerror() facilitates this.
