erf(3) -- error function operators
|
|
These functions calculate the error function of x. The erf() calculates the error function of x; where erf(x) = 2/sqrt(pi)*integral from 0 to x of exp(-t*t) dt. The erfc() function calculates the comp... |

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, a colon character, and a space are output... |
|
error_message(3) -- common error display library
|
|
The com_err library provides a common error-reporting mechanism for defining and accessing error codes and descriptions for application software packages. Error descriptions are defined in a table and... |

|
errx(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, a colon character, and a space are output... |
|
ERR_clear_error(3) -- clear the error queue
|
|
ERR_clear_error() empties the current thread's error queue. |
|
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_get_error(3) -- obtain error code and data
|
|
ERR_get_error() returns the last 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_error()... |
|
ERR_GET_LIB(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... |
|
ERR_load_crypto_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... |
