# gnutls\_priority\_init(3)

API function

## NAME

gnutls\_priority\_init - API function

## SYNOPSIS

**#include \<gnutls/gnutls.h\>**

**int gnutls\_priority\_init(gnutls\_priority\_t \*** *priority\_cache***, const char \*** *priorities***, const char \*\*** *err\_pos***);**

## ARGUMENTS

- gnutls\_priority\_t \* priority\_cache

  is a **gnutls\_priority\_t** type.

- const char \* priorities

  is a string describing priorities (may be **NULL**)

- const char \*\* err\_pos

  In case of an error this will have the position in the string the error occurred

## DESCRIPTION

For applications that do not modify their crypto settings per release, consider using **gnutls\_priority\_init2()** with **GNUTLS\_PRIORITY\_INIT\_DEF\_APPEND** flag instead. We suggest to use centralized crypto settings handled by the GnuTLS library, and applications modifying the default settings to their needs.

This function is identical to **gnutls\_priority\_init2()** with zero flags.

A **NULL**  *priorities* string indicates the default priorities to be used (this is available since GnuTLS 3.3.0).

## RETURNS

On syntax error **GNUTLS\_E\_INVALID\_REQUEST** is returned, **GNUTLS\_E\_SUCCESS** on success, or an error code.
