ERR_set_mark(3)              OpenSSL              ERR_set_mark(3)

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.
