Parameters

VariablesDescription
location
Specifies the location of the uniform variable to be modified.
count
For the vector ( glUniform*v ) commands, specifies the number of elements that are to be modified. This should be 1 if the targeted uniform variable is not an array, and 1 or more if it is an array.
transpose
For the matrix commands, specifies whether to transpose the matrix as the values are loaded into the uniform variable.
v0, v1, v2, v3
For the scalar commands, specifies the new values to be used for the specified uniform variable.
value
For the vector and matrix commands, specifies a pointer to an array of count values that will be used to update the specified uniform variable.
