ERR_new(3)                          OpenSSL                         ERR_new(3)



NAME
       ERR_new, ERR_set_debug, ERR_set_error, ERR_vset_error - Error recording
       building blocks

LIBRARY
       libcrypto, -lcrypto

SYNOPSIS
        #include <openssl/err.h>

        void ERR_new(void);
        void ERR_set_debug(const char *file, int line, const char *func);
        void ERR_set_error(int lib, int reason, const char *fmt, ...);
        void ERR_vset_error(int lib, int reason, const char *fmt, va_list args);

DESCRIPTION
       The functions described here are generally not used directly, but
       rather through macros such as ERR_raise(3).  They can still be useful
       for anyone that wants to make their own macros.

       ERR_new() allocates a new slot in the thread's error queue.

       ERR_set_debug() sets the debug information related to the current error
       in the thread's error queue.  The values that can be given are the
       filename file, line in the file line and the name of the function func
       where the error occurred.  The names must be constant, this function
       will only save away the pointers, not copy the strings.

       ERR_set_error() sets the error information, which are the library
       number lib and the reason code reason, and additional data as a format
       string fmt and an arbitrary number of arguments.  The additional data
       is processed with BIO_snprintf(3) to form the additional data string,
       which is allocated and store in the error record.

       ERR_vset_error() works like ERR_set_error(), but takes a va_list
       argument instead of a variable number of arguments.

RETURN VALUES
       ERR_new, ERR_set_debug, ERR_set_error and ERR_vset_error do not return
       any values.

NOTES
       The library number is unique to each unit that records errors.  OpenSSL
       has a number of preallocated ones for its own uses, but others may
       allocate their own library number dynamically with
       ERR_get_next_error_library(3).

       Reason codes are unique within each library, and may have an associated
       set of strings as a short description of the reason.  For dynamically
       allocated library numbers, reason strings are recorded with
       ERR_load_strings(3).

       Provider authors are supplied with core versions of these functions,
       see provider-base(7).
