glGetActiveSubroutineName - query the name of an active shader subroutine
GLenum shadertype, GLuint index,
GLsizei bufSize, GLsizei *length,
Specifies the name of the program containing the
Specifies the shader stage from which to query the
Specifies the index of the shader subroutine
Specifies the size of the buffer whose address is given
Specifies the address of a variable which is to receive
the length of the shader subroutine uniform name.
Specifies the address of an array into which the name of
the shader subroutine uniform will be written.
glGetActiveSubroutineName queries the name of an active shader subroutine
uniform from the program object given in program. index
specifies the index of the shader subroutine uniform within the shader stage
given by stage, and must between zero and the value of
GL_ACTIVE_SUBROUTINES minus one for the shader stage.
The name of the selected subroutine is returned as a
null-terminated string in name. The actual number of characters
written into name, not including the null-terminator, is returned in
length. If length is NULL, no length is returned. The
maximum number of characters that may be written into name, including
the null-terminator, is given in bufSize.
GL_INVALID_VALUE is generated if index is greater than or equal to
the value of GL_ACTIVE_SUBROUTINES.
GL_INVALID_VALUE is generated if program is not the
name of an existing program object.
