cgGetNamedEffectParameter(3)

NAME
cgGetNamedEffectParameter - get an effect parameter by name

SYNOPSIS
  #include <Cg/cg.h>
  CGparameter cgGetNamedEffectParameter( CGeffect effect,
                                         const char * name );

PARAMETERS
The effect from which to retrieve the parameter. The name of the parameter to retrieve.

RETURN VALUES
Returns the named parameter from the effect.

Returns NULL if the effect has no parameter corresponding to name.

DESCRIPTION
The parameters of a effect can be retrieved directly by name using cgGetNamedEffectParameter. The names of the parameters in a effect can be discovered by iterating through the effect's parameters (see the cgGetFirstEffectParameter manpage and the cgGetNextEffectParameter manpage), calling the cgGetParameterName manpage for each one in turn.

The given name may be of the form "foo.bar[2]", which retrieves the second element of the array "bar" in a structure named "foo".

EXAMPLES

ERRORS
CG_INVALID_EFFECT_HANDLE_ERROR is generated if effect is not a valid effect.

HISTORY
cgGetNamedEffectParameter was introduced in Cg 1.4.
