ERR_SET_MARK(3) Library Functions Manual ERR_SET_MARK(3)

ERR_set_mark, ERR_pop_to_markset marks and pop OpenSSL errors until mark

#include <openssl/err.h>



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

() 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.

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

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


ERR_set_mark() and ERR_pop_to_mark() were added in OpenSSL 0.9.8.
