GLOBJECTLABEL(3G) OpenGL Manual GLOBJECTLABEL(3G) NAME
glObjectLabel - label a named object identified within a namespace C SPECIFICATION
void glObjectLabel(GLenum identifier, GLuint name, GLsizei length, const char * label); PARAMETERS
identifier The namespace from which the name of the object is allocated. name The name of the object to label. length The length of the label to be used for the object. label The address of a string containing the label to assign to the object. DESCRIPTION
glObjectLabel labels 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 label an object. length contains the number of characters in label. If length is negative, it is implied that label contains a null-terminated string. If label is NULL, any debug label is effectively removed from the object. 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 the number of characters in label, excluding the null terminator when length is negative, is greater than the value of GL_MAX_LABEL_LENGTH. ASSOCIATED GETS

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
