NAMEglGetObjectLabel − retrieve the label of a named object identified within a namespace

C SPECIFICATIONvoid glGetObjectLabel(GLenum identifier, GLuint name, GLsizei bufSize, GLsizei * length, char * label);

PARAMETERSidentifier The namespace from which the name of the object is allocated​. name The name of the object whose label to retrieve​. bufSize The length of the buffer whose address is in label​. length The address of a variable to receive the length of the object label​. label The address of a string that will receive the object label​.

DESCRIPTIONglGetObjectLabel retrieves the label of the object identified by name within the namespace given by identifier​. identifier must be one of GL_BUFFER, GL_SHADER, GL_PROGRAM, GL_VERTEX_ARRAY, GL_QUERY, GL_PROGRAM_PIPELINE, GL_TRANSFORM_FEEDBACK, GL_SAMPLER, GL_TEXTURE, GL_RENDERBUFFER, GL_FRAMEBUFFER, to indicate the namespace containing the names of buffers, shaders, programs, vertex array objects, query objects, program pipelines, transform feedback objects, samplers, textures, renderbuffers and frame buffers, respectively​. label is the address of a string that will be used to store the object label​. bufSize specifies the number of characters in the array identified by label​. length contains the address of a variable which will receive the number of characters in the object label​. If length is NULL, then it is ignored and no data is written​. Likewise, if label is NULL, or if bufSize is zero then no data is written to label​.

ERRORSGL_INVALID_ENUM is generated if identifier is not one of the accepted object types​. GL_INVALID_OPERATION is generated if name is not the name of an existing object of the type specified by identifier​. GL_INVALID_VALUE is generated if bufSize is zero​. If not NULL, length and label should be addresses to which the client has write access, otherwise undefined behavior, including process termination may occur​.

ASSOCIATED GETSglGet() with argument GL_MAX_LABEL_LENGTH​.
