59 .Nd get library, function and reason codes for OpenSSL errors
79 The error code returned by
81 consists of a library number, function code, and reason code.
86 can be used to extract these.
88 The library number and function code describe where the error occurred,
89 whereas the reason code is the information about what went wrong.
91 Each sub-library of OpenSSL has a unique library number; function and
92 reason codes are unique within each sub-library.
93 Note that different libraries may use the same value to signal different
94 functions and reasons.
98 .Dv ERR_R_MALLOC_FAILURE
100 However, when checking for sub-library specific reason codes, be sure to
101 also compare the library number.
104 indicates whether a given error code is a fatal error.
106 These functions are implemented as macros.
112 return the library number, function code, and reason code, respectively.
115 returns non-zero if the error is fatal or 0 otherwise.
124 are available in all versions of SSLeay and OpenSSL.
