NAME

ERR_set_mark, ERR_pop_to_mark - set marks and pop errors until mark

LIBRARY

libcrypto, -lcrypto

SYNOPSIS


 #include 


 int ERR_set_mark(void);


 int ERR_pop_to_mark(void);

DESCRIPTION

_E_R_R___s_e_t___m_a_r_k_(_) sets a mark on the current topmost error record if there is one.

_E_R_R___p_o_p___t_o___m_a_r_k_(_) will pop the top of the error stack until a mark is found. The mark is then removed. If there is no mark, the whole stack is removed.

RETURN VALUES

_E_R_R___s_e_t___m_a_r_k_(_) returns 0 if the error stack is empty, otherwise 1.

_E_R_R___p_o_p___t_o___m_a_r_k_(_) returns 0 if there was no mark in the error stack, which implies that the stack became empty, otherwise 1.
