gnutls_x509_crt_get_issuer_unique_id - API function
Синопсис (Synopsis)
#include <gnutls/x509.h>
int gnutls_x509_crt_get_issuer_unique_id(gnutls_x509_crt_t crt,
char * buf, size_t * buf_size);
Аргументы (Arguments)
gnutls_x509_crt_t crt
Holds the certificate
char * buf user allocated memory buffer, will hold the unique id
size_t * buf_size
size of user allocated memory buffer (on input), will
hold actual size of the unique ID on return.
Описание (Description)
This function will extract the issuerUniqueID value (if present)
for the given certificate.
If the user allocated memory buffer is not large enough to hold
the full subjectUniqueID, then a GNUTLS_E_SHORT_MEMORY_BUFFER
error will be returned, and buf_size will be set to the actual
length.
This function had a bug prior to 3.4.8 that prevented the setting
of NULL buf to discover the buf_size . To use this function
safely with the older versions the buf must be a valid buffer
that can hold at least a single byte if buf_size is zero.
Возвращаемое значение (Return value)
GNUTLS_E_SUCCESS on success, otherwise a negative error code.
