cgGetNamedStructParameter

NAME

cgGetNamedStructParameter - get a struct parameter by name

SYNOPSIS

  #include <Cg/cg.h>

  CGparameter cgGetNamedStructParameter( CGparameter param,

                                         const char * name );

PARAMETERS

param

The struct parameter from which to retrieve the member parameter.

name

The name of the member parameter to retrieve.

RETURN VALUES

Returns the member parameter from the given struct.

Returns NULL if the struct has no member parameter corresponding to name.

DESCRIPTION

The member parameters of a struct parameter may be retrieved directly by name using cgGetNamedStructParameter.

The names of the parameters in a struct may be discovered by iterating through the struct's member parameters (see cgGetFirstStructParameter and cgGetNextParameter), and calling cgGetParameterName for each one in turn.

EXAMPLES

to-be-written

ERRORS

CG_INVALID_PARAM_HANDLE_ERROR is generated if param is not a valid parameter.

CG_INVALID_PARAMETER_TYPE_ERROR is generated if param is not a struct parameter.

HISTORY

cgGetNamedStructParameter was introduced in Cg 1.2.
