gnutls_x509_cr...extension_info(3) gnutls gnutls_x509_cr...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, unsigned indx, void * oid, size_t * oid_size, unsigned int * critical); ARGUMENTS gnutls_x509_crt_t cert should contain a gnutls_x509_crt_t type unsigned 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 certifi- cate, and the critical flag for it. The extension OID will be stored as a string in the provided buffer. Use gnutls_x509_crt_get_exten- sion() 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 (the latter is not true for GnuTLS prior to 3.6.0). RETURNS On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative er- ror code is returned. If you have reached the last extension available GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned. REPORTING BUGS Report bugs to <bugs@gnutls.org>.
