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.

NAME

       glGetSynciv - query the properties of a sync object

C SPECIFICATION

       void glGetSynciv(GLsync sync, GLenum pname, GLsizei bufSize, GLsizei *length, GLint *values);

PARAMETERS

       sync
	   Specifies the sync object whose properties to query.

       pname
	   Specifies the parameter whose value to retrieve from the sync object specified in sync.

       bufSize
	   Specifies the size of the buffer whose address is given in values.

       length
	   Specifies the address of an variable to receive the number of integers placed in values.

       values
	   Specifies the address of an array to receive the values of the queried parameter.

DESCRIPTION

       glGetSynciv retrieves properties of a sync object.  sync specifies the name of the sync object whose properties to retrieve.

       On success, glGetSynciv replaces up to bufSize integers in values with the corresponding property values of the object being queried. The
       actual number of integers replaced is returned in the variable whose address is specified in length. If length is NULL, no length is
       returned.

       If pname is GL_OBJECT_TYPE, a single value representing the specific type of the sync object is placed in values. The only type supported
       is GL_SYNC_FENCE.

       If pname is GL_SYNC_STATUS, a single value representing the status of the sync object (GL_SIGNALED or GL_UNSIGNALED) is placed in values.

       If pname is GL_SYNC_CONDITION, a single value representing the condition of the sync object is placed in values. The only condition
       supported is GL_SYNC_GPU_COMMANDS_COMPLETE.

       If pname is GL_SYNC_FLAGS, a single value representing the flags with which the sync object was created is placed in values. No flags are
       currently supported[1].

       If an error occurs, nothing will be written to values or length.

ERRORS

       GL_INVALID_VALUE is generated if sync is not the name of a sync object.

       GL_INVALID_ENUM is generated if pname is not one of the accepted tokens.

NOTES

	1. flags is expected to be used in future extensions to the sync objects.
