get library, function and reason codes for OpenSSL errors
ERR_GET_LIB(unsigned long e); int
ERR_GET_FUNC(unsigned long e); int
ERR_GET_REASON(unsigned long e); int
ERR_FATAL_ERROR(unsigned long e); ERR_get_error(3) consists of a library number, function code, and reason code.
ERR_GET_REASON() can be used to extract these. The library number and function code describe where the error occurred, whereas the reason code is the information about what went wrong. 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.
ERR_R_*reason codes such as
ERR_R_MALLOC_FAILUREare globally unique. However, when checking for sub-library specific reason codes, be sure to also compare the library number.
ERR_FATAL_ERROR() indicates whether a given error code is a fatal error. These functions are implemented as macros.
ERR_GET_REASON() return the library number, function code, and reason code, respectively.
ERR_FATAL_ERROR() returns non-zero if the error is fatal or 0 otherwise. ERR(3), ERR_get_error(3)
ERR_FATAL_ERROR() first appeared in SSLeay 0.4.4 and have been available since OpenBSD 2.4.
