NAME¶
glUniformSubroutines - load active subroutine uniforms
C SPECIFICATION¶
void
glUniformSubroutinesuiv(GLenum shadertype,
GLsizei count,
const GLuint *indices);
PARAMETERS¶
shadertype
Specifies the shader stage from which to query
for subroutine uniform index. shadertype must be one of
GL_VERTEX_SHADER, GL_TESS_CONTROL_SHADER,
GL_TESS_EVALUATION_SHADER, GL_GEOMETRY_SHADER or
GL_FRAGMENT_SHADER.
count
Specifies the number of uniform indices stored
in indices.
indices
Specifies the address of an array holding the
indices to load into the shader subroutine variables.
DESCRIPTION¶
glUniformSubroutines loads all active subroutine uniforms for shader
stage
shadertype of the current program with subroutine indices from
indices, storing
indices[i] into the uniform at location
i.
count must be equal to the value of
GL_ACTIVE_SUBROUTINE_UNIFORM_LOCATIONS for the program currently in use
at shader stage
shadertype. Furthermore, all values in
indices
must be less than the value of
GL_ACTIVE_SUBROUTINES for the shader
stage.
ERRORS¶
GL_INVALID_OPERATION is generated if no program object is current.
GL_INVALID_VALUE is generated if
count is not equal to the value
of
GL_ACTIVE_SUBROUTINE_UNIFORM_LOCATIONS for the shader stage
shadertype of the current program.
GL_INVALID_VALUE is generated if any value in
indices is geater
than or equal to the value of
GL_ACTIVE_SUBROUTINES for the shader
stage
shadertype of the current program.
GL_INVALID_ENUM is generated if
shadertype is not one of the
accepted values.
