|
|
The error code returned by \fIERR_get_error()\fR consists of a library
|
|
number, function code and reason code. \s-1\fIERR_GET_LIB\s0()\fR, \s-1\fIERR_GET_FUNC\s0()\fR
|
|
and \s-1\fIERR_GET_REASON\s0()\fR can be used to extract these.
|
|
.PP
|
|
The library number and function code describe where the error
|
|
occurred, the reason code is the information about what went wrong.
|
|
.PP
|
|
Each sub-library of OpenSSL has a unique library number; function and
|
|
reason codes are unique within each sub\-library. Note that different
|
|
libraries may use the same value to signal different functions and
|
|
reasons.
|
|
.PP
|
|
\&\fB\s-1ERR_R_\s0...\fR reason codes such as \fB\s-1ERR_R_MALLOC_FAILURE\s0\fR are globally
|
|
unique. However, when checking for sub-library specific reason codes,
|
|
be sure to also compare the library number.
