glGetObjectLabel — retrieve the label of a named object identified within a namespace
| ||GLenum identifier,|
|GLsizei * length,|
|char * label |
The namespace from which the name of the object is allocated.
The name of the object whose label to retrieve.
The length of the buffer whose address is in
The address of a variable to receive the length of the object label.
The address of a string that will receive the object label.
glGetObjectLabel retrieves the label of the object identified by
name within the namespace given by
identifier must be one of
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
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
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
GL_INVALID_VALUE is generated if
bufSize is zero.
If not NULL,
label should be addresses to which the client has write access, otherwise undefined behavior, including process termination may occur.
