Error Codes

Most functions in the Emergent SDK (eSDK) API return an error code of type EVT_ERROR, indicating the success or failure of the operation. Error codes are documented alongside each function in eSDK API Functions.

Below is a summary of possible error codes for reference:

• EVT_SUCCESS: Function executed successfully.
• EVT_ERROR_SRCH: Parameter not found; usually indicates an invalid or unsupported parameter.
• EVT_ERROR_INTR: An interrupt signal was received, terminating the function.
• EVT_ERROR_IO: Input/Output error, typically related to file operations.
• EVT_ERROR_AGAIN: Timeout expired; consider increasing the timeout or reissuing the command.
• EVT_ERROR_NOMEM: Out of memory; try freeing up memory or optimizing memory usage.
• EVT_ERROR_INVAL: Invalid argument; check parameter values for correctness.
• EVT_ERROR_NOT_SUPPORTED: Unsupported buffer type or feature.
• EVT_ERROR_DEVICE_CONNECTED_ALRD: Device already opened; close the connection before reattempting.
• EVT_ERROR_DEVICE_NOT_CONNECTED: Device not open; ensure the device is properly connected and initialized.
• EVT_ERROR_DEVICE_LOST_CONNECTION: Lost connection to the device; verify network stability.
• EVT_ERROR_GENICAM_ERROR: GenICam-specific error; may relate to camera-specific settings.
• EVT_ERROR_GENICAM_NOT_MATCH: Parameter type mismatch with GenICam standards.
• EVT_ERROR_GENICAM_OUT_OF_RANGE: Parameter value is outside the acceptable range.
• EVT_ERROR_SOCK: Socket error, often indicating network or connection issues.
• EVT_ERROR_GVCP_ACK: Error with GVCP (GigE Vision Control Protocol) acknowledgment.
• EVT_ERROR_GVSP_DATA_CORRUPT: Frame data corruption in GVSP (GigE Vision Streaming Protocol).
• EVT_ERROR_NIC_LIB_INIT: Failed to initialize Myricom NIC API.
• EVT_ERROR_OS_OBTAIN_ADAPTER: Failed to retrieve host adapter information.
• EVT_ERROR_SDK: An unexpected SDK-related error.
• EVT_GENERAL_ERROR: General error; indicates an undefined issue, often resolved by reviewing function parameters or connection stability.
