Method
CoglPipelineget_uniform_location
Declaration [src]
int
cogl_pipeline_get_uniform_location (
CoglPipeline* pipeline,
const char* uniform_name
)
Description [src]
This is used to get an integer representing the uniform with the
name uniform_name. The integer can be passed to functions such as
cogl_pipeline_set_uniform_1f() to set the value of a uniform.
This function will always return a valid integer. Ie, unlike OpenGL, it does not return -1 if the uniform is not available in this pipeline so it can not be used to test whether uniforms are present. It is not necessary to set the program on the pipeline before calling this function.
