gnutls_ocsp_resp_get_extension(3) gnutls gnutls_ocsp_resp_get_extension(3) NAME
gnutls_ocsp_resp_get_extension - API function SYNOPSIS
#include <gnutls/ocsp.h> int gnutls_ocsp_resp_get_extension(gnutls_ocsp_resp_t resp, unsigned indx, gnutls_datum_t * oid, unsigned int * critical, gnutls_datum_t * data); ARGUMENTS
gnutls_ocsp_resp_t resp should contain a gnutls_ocsp_resp_t structure unsigned indx Specifies which extension OID to get. Use (0) to get the first one. gnutls_datum_t * oid will hold newly allocated buffer with OID of extension, may be NULL unsigned int * critical output variable with critical flag, may be NULL. gnutls_datum_t * data will hold newly allocated buffer with extension data, may be NULL DESCRIPTION
This function will return all information about the requested extension in the OCSP response. The information returned is the OID, the critical flag, and the data itself. The extension OID will be stored as a string. Any of oid , critical , and data may be NULL which means that the caller is not interested in getting that information back. The caller needs to deallocate memory by calling gnutls_free() on oid ->data and data ->data. RETURNS
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error code is returned. If you have reached the last extension avail- able GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned. REPORTING BUGS

gnutls_x509_crt_get_extension_info(3) gnutls gnutls_x509_crt_get_extension_info(3) NAME
gnutls_x509_crt_get_extension_info - API function SYNOPSIS
#include <gnutls/x509.h> int gnutls_x509_crt_get_extension_info(gnutls_x509_crt_t cert, int indx, void * oid, size_t * oid_size, unsigned int * critical); ARGUMENTS
gnutls_x509_crt_t cert should contain a gnutls_x509_crt_t structure int indx Specifies which extension OID to send. Use (0) to get the first one. void * oid a pointer to a structure to hold the OID size_t * oid_size initially holds the maximum size of oid , on return holds actual size of oid . unsigned int * critical output variable with critical flag, may be NULL. DESCRIPTION
This function will return the requested extension OID in the certificate, and the critical flag for it. The extension OID will be stored as a string in the provided buffer. Use gnutls_x509_crt_get_extension_data() to extract the data. If the buffer provided is not long enough to hold the output, then oid_size is updated and GNUTLS_E_SHORT_MEMORY_BUFFER will be returned. The oid returned will be null terminated, although oid_size will not account for the trailing null. RETURNS
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error code is returned. If you have reached the last extension avail- able GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned. REPORTING BUGS
