err(3) -- formatted error messages
|
|
The err() and warn() family of functions display a formatted error message on the standard error output. In all cases, the last component of the program name, followed by a colon (`:') character and ... |

ERR_add_error_data(3) -- record an error
|
|
ERR_put_error() adds an error code to the thread's error queue. It signals that the error of reason code reason occurred in function func of library lib, in line number line of file. This function is... |

ERR_error_string(3) -- obtain human-readable error message
|
|
ERR_error_string() generates a human-readable string representing the error code e, and places it at buf. buf must be at least 120 bytes long. If buf is NULL, the error string is placed in a static bu... |

ERR_error_string_n(3) -- obtain human-readable error message
|
|
ERR_error_string() generates a human-readable string representing the error code e, and places it at buf. buf must be at least 120 bytes long. If buf is NULL, the error string is placed in a static bu... |
|
ERR_free_strings(3) -- load and free error strings
|
|
ERR_load_crypto_strings() registers the error strings for all libcrypto functions. SSL_load_error_strings() does the same, but also registers the libssl error strings. One of these functions should be... |

ERR_get_error(3) -- obtain error code and data
|
|
ERR_get_error() returns the earliest error code from the thread's error queue and removes the entry. This function can be called repeatedly until there are no more error codes to return. ERR_peek_err... |

|
ERR_GET_FUNC(3) -- get library, function and reason code
|
|
The error code returned by ERR_get_error() consists of a library number, function code and reason code. ERR_GET_LIB(), ERR_GET_FUNC() and ERR_GET_REASON() can be used to extract these. The library num... |
