GLGETUNIFORMINDICES(3G) 		  OpenGL Manual 		  GLGETUNIFORMINDICES(3G)

NAME
       glGetUniformIndices - retrieve the index of a named uniform block

C SPECIFICATION
       void glGetUniformIndices(GLuint program, GLsizei uniformCount,
				const GLchar **uniformNames, GLuint *uniformIndices);

PARAMETERS
       program
	   Specifies the name of a program containing uniforms whose indices to query.

       uniformCount
	   Specifies the number of uniforms whose indices to query.

       uniformNames
	   Specifies the address of an array of pointers to buffers containing the names of the
	   queried uniforms.

       uniformIndices
	   Specifies the address of an array that will receive the indices of the uniforms.

DESCRIPTION
       glGetUniformIndices retrieves the indices of a number of uniforms within program.

       program must be the name of a program object for which the command glLinkProgram() must
       have been called in the past, although it is not required that glLinkProgram() must have
       succeeded. The link could have failed because the number of active uniforms exceeded the
       limit.

       uniformCount indicates both the number of elements in the array of names uniformNames and
       the number of indices that may be written to uniformIndices.

       uniformNames contains a list of uniformCount name strings identifying the uniform names to
       be queried for indices. For each name string in uniformNames, the index assigned to the
       active uniform of that name will be written to the corresponding element of
       uniformIndices. If a string in uniformNames is not the name of an active uniform, the
       special value GL_INVALID_INDEX will be written to the corresponding element of
       uniformIndices.

       If an error occurs, nothing is written to uniformIndices.

ERRORS
       GL_INVALID_OPERATION is generated if program is not the name of a program object for which
       glLinkProgram() has been called in the past.

NOTES
       glGetUniformIndices is available only if the GL version is 3.1 or greater.
