GLGETOBJECTLABEL(3G) OpenGL Manual GLGETOBJECTLABEL(3G)
NAME
glGetObjectLabel - retrieve the label of a named object identified within a namespace
C SPECIFICATION
void glGetObjectLabel(GLenum identifier, GLuint name, GLsizei bifSize, GLsizei * length,
char * label);
PARAMETERS
identifier
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.
DESCRIPTION
glGetObjectLabel 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 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.
ERRORS
GL_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 GETS
glGet() with argument GL_MAX_LABEL_LENGTH.
