NAME

6       gnutls_x509_crq_get_basic_constraints  -  get  certificate's basic con‐
7       straints
8

SYNOPSIS

10       #include <gnutls/x509.h>
11
12       int    gnutls_x509_crq_get_basic_constraints(gnutls_x509_crq_t    cert,
13       unsigned int * critical, int * ca, int * pathlen);
14

ARGUMENTS

16       gnutls_x509_crq_t cert
17                   should contain a gnutls_x509_crq_t structure
18
19       unsigned int * critical
20                   will be non zero if the extension is marked as critical
21
22       int * ca    pointer  to  output  integer  indicating  CA status, may be
23                   NULL, value is 1 if the certificate CA flag is set, 0  oth‐
24                   erwise.
25
26       int * pathlen
27                   pointer  to  output  integer indicating path length (may be
28                   NULL), non-negative values indicate a  present  pathLenCon‐
29                   straint  field  and  the actual value, -1 indicate that the
30                   field is absent.
31

DESCRIPTION

33       This function will read the certificate's basic constraints, and return
34       the certificates CA status.  It reads the basicConstraints X.509 exten‐
35       sion (2.5.29.19).
36

RETURN VALUE

38       If the certificate is a CA a positive value will be returned,  or  zero
39       if  the certificate does not have CA flag set.  A negative value may be
40       returned in case of errors.  If the certificate does  not  contain  the
41       basicConstraints  extension  GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will
42       be returned.
