.SH "NAME"
glGetShaderSource \- Returns the source code string from a shader object
.SH "C SPECIFICATION"
.HP \w'void\ glGetShaderSource('u
.BI "void glGetShaderSource(GLuint\ " "shader" ", GLsizei\ " "bufSize" ", GLsizei\ *" "length" ", GLchar\ *" "source" ");"
.SH "PARAMETERS"
.PP
\fIshader\fR
.RS 4
Specifies the shader object to be queried\&.
.RE
.PP
\fIbufSize\fR
.RS 4
Specifies the size of the character buffer for storing the returned source code string\&.
.RE
.PP
\fIlength\fR
.RS 4
Returns the length of the string returned in
\fIsource\fR
(excluding the null terminator)\&.
.RE
.PP
\fIsource\fR
.RS 4
Specifies an array of characters that is used to return the source code string\&.
.RE
.SH "DESCRIPTION"
.PP
\fBglGetShaderSource\fR
returns the concatenation of the source code strings from the shader object specified by
\fIshader\fR\&. The source code strings for a shader object are the result of a previous call to
\fBglShaderSource\fR()\&. The string returned by the function will be null terminated\&.
.PP
\fBglGetShaderSource\fR
returns in
\fIsource\fR
as much of the source code string as it can, up to a maximum of
\fIbufSize\fR
characters\&. The number of characters actually returned, excluding the null termination character, is specified by
\fIlength\fR\&. If the length of the returned string is not required, a value of
\fBNULL\fR
can be passed in the
\fIlength\fR
argument\&. The size of the buffer required to store the returned source code string can be obtained by calling
\fBglGetShader\fR()
with the value
\fBGL_SHADER_SOURCE_LENGTH\fR\&.
.SH "ERRORS"
.PP
\fBGL_INVALID_VALUE\fR
is generated if
\fIshader\fR
is not a value generated by OpenGL\&.
.PP
\fBGL_INVALID_OPERATION\fR
is generated if
\fIshader\fR
is not a shader object\&.
.PP
\fBGL_INVALID_VALUE\fR
is generated if
\fIbufSize\fR
is less than 0\&.
.SH "ASSOCIATED GETS"
