glShaderSource
Replaces the source code in a shader object
C Specification
void glShaderSource
GLuint shader
GLsizei count
const GLchar **string
const GLint *length
Parameters
shader
Specifies the handle of the shader object
whose source code is to be replaced.
count
Specifies the number of elements in the
string and
length
arrays.
string
Specifies an array of pointers to strings
containing the source code to be loaded into the
shader.
length
Specifies an array of string lengths.
Description
glShaderSource sets the source code
in shader to the source code in the array
of strings specified by string. Any
source code previously stored in the shader object is completely
replaced. The number of strings in the array is specified by
count. If length
is NULL, each string is assumed to be null
terminated. If length is a value other
than NULL, it points to an array containing
a string length for each of the corresponding elements of
string. Each element in the
length array may contain the length of
the corresponding string (the null character is not counted as
part of the string length) or a value less than 0 to indicate
that the string is null terminated. The source code strings are
not scanned or parsed at this time; they are simply copied into
the specified shader object.
Notes
OpenGL copies the shader source code strings when
glShaderSource is called, so an application
may free its copy of the source code strings immediately after
the function returns.
Errors
GL_INVALID_VALUE is generated if
shader is not a value generated by
OpenGL.
GL_INVALID_OPERATION is generated if
shader is not a shader object.
GL_INVALID_VALUE is generated if
count is less than 0.
