5 ERR_set_mark, ERR_clear_last_mark, ERR_pop_to_mark
6 - set mark, clear mark and pop errors until mark
10 #include <openssl/err.h>
12 int ERR_set_mark(void);
13 int ERR_pop_to_mark(void);
14 int ERR_clear_last_mark(void);
18 ERR_set_mark() sets a mark on the current topmost error record if there
21 ERR_pop_to_mark() will pop the top of the error stack until a mark is found.
22 The mark is then removed. If there is no mark, the whole stack is removed.
24 ERR_clear_last_mark() removes the last mark added if there is one.
28 ERR_set_mark() returns 0 if the error stack is empty, otherwise 1.
30 ERR_clear_last_mark() and ERR_pop_to_mark() return 0 if there was no mark in the
31 error stack, which implies that the stack became empty, otherwise 1.
