GLGETUNIFORMINDICES(3G) OpenGL 3.3 GLGETUNIFORMINDICES(3G) NAME
glGetUniformIndices - retrieve the index of a named uniform block C SPECIFICATION
GLuint 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. SEE ALSO
