ERR_NEW(3ossl) OpenSSL ERR_NEW(3ossl)
NAME
ERR_new, ERR_set_debug, ERR_set_error, ERR_vset_error - Error recording
building blocks
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).
