.SH NAME
gnutls_x509_crq_get_key_purpose_oid \- API function
.SH SYNOPSIS
.B #include <gnutls/x509.h>
.sp
.BI "int gnutls_x509_crq_get_key_purpose_oid(gnutls_x509_crq_t " crq ", unsigned " indx ", void * " oid ", size_t * " sizeof_oid ", unsigned int * " critical ");"
.SH ARGUMENTS
.IP "gnutls_x509_crq_t crq" 12
should contain a \fBgnutls_x509_crq_t\fP type
.IP "unsigned indx" 12
This specifies which OID to return, use (0) to get the first one
.IP "void * oid" 12
a pointer to store the OID (may be \fBNULL\fP)
.IP "size_t * sizeof_oid" 12
initially holds the size of  \fIoid\fP 
.IP "unsigned int * critical" 12
output variable with critical flag, may be \fBNULL\fP.
.SH "DESCRIPTION"

human readable names.
.SH "RETURNS"
\fBGNUTLS_E_SHORT_MEMORY_BUFFER\fP if the provided buffer is
not long enough, and in that case the * \fIsizeof_oid\fP will be
