NAME
cgGetNamedEffectParameter - get a effect parameter by name
SYNOPSIS
#include <Cg/cg.h> CGparameter cgGetNamedEffectParameter( CGeffect effect, const char * name );PARAMETERS
- effect
Specifies the effect to retrieve the parameter from.
- name
Specifies the name of the parameter to retrieve.
DESCRIPTION
The parameters of a effect can be retrieved directly by name using the cgGetNamedEffectParameter function. The names of the parameters in a effect can be discovered by iterating through the effect's parameters (see cgGetFirstEffectParameter and cgGetNextEffectParameter), calling cgGetParameterName 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".
RETURN VALUES
Returns the named parameter from the effect. If the effect has no parameter corresponding to name, NULL is returned.
ERRORS
CG_INVALID_EFFECT_HANDLE_ERROR is generated if effect does not refer to a valid effect.
