ERR_GET_LIB 3 2000-07-16 0.9.9-dev OpenSSL

NAME

ERR_GET_LIB, ERR_GET_FUNC, ERR_GET_REASON - get library, function and reason code

LIBRARY

libcrypto, -lcrypto

SYNOPSIS


 #include 


 int ERR_GET_LIB(unsigned long e);


 int ERR_GET_FUNC(unsigned long e);


 int ERR_GET_REASON(unsigned long e);

DESCRIPTION

The error code returned by _E_R_R___g_e_t___e_r_r_o_r_(_) consists of a library number, function code and reason code. _E_R_R___G_E_T___L_I_B_(_), _E_R_R___G_E_T___F_U_N_C_(_) and _E_R_R___G_E_T___R_E_A_S_O_N_(_) can be used to extract these.

The library number and function code describe where the error occurred, 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.

EERRRR__RR__...... reason codes such as EERRRR__RR__MMAALLLLOOCC__FFAAIILLUURREE are globally unique. However, when checking for sub-library specific reason codes, be sure to also compare the library number.

_E_R_R___G_E_T___L_I_B_(_), _E_R_R___G_E_T___F_U_N_C_(_) and _E_R_R___G_E_T___R_E_A_S_O_N_(_) are macros.

RETURN VALUES

The library number, function code and reason code respectively.

HISTORY
