ERR_set_mark(3) OpenSSL ERR_set_mark(3) NAME ERR_set_mark, ERR_clear_last_mark, ERR_pop_to_mark - set mark, clear mark and pop errors until mark LIBRARY libcrypto, -lcrypto SYNOPSIS #include <openssl/err.h> int ERR_set_mark(void); int ERR_pop_to_mark(void); int ERR_clear_last_mark(void); DESCRIPTION ERR_set_mark() sets a mark on the current topmost error record if there is one. ERR_pop_to_mark() 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_clear_last_mark() removes the last mark added if there is one. RETURN VALUES ERR_set_mark() returns 0 if the error stack is empty, otherwise 1. ERR_clear_last_mark() and ERR_pop_to_mark() return 0 if there was no mark in the error stack, which implies that the stack became empty, otherwise 1.
