# NAME

ERR_set_mark, ERR_pop_to_mark - set marks and pop errors until mark

# SYNOPSIS

     #include <openssl/err.h>

     int ERR_set_mark(void);

     int ERR_pop_to_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.

# RETURN VALUES

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.
