.SH "NAME"
glShaderSource \- Replaces the source code in a shader object

.SH "PARAMETERS"
.PP
\fIshader\fR

Specifies the handle of the shader object whose source code is to be replaced\&.
.RE
.PP
\fIcount\fR
.RS 4
Specifies the number of elements in the
\fIstring\fR
and
\fIlength\fR
arrays\&.

.PP
\fIstring\fR

Specifies an array of pointers to strings containing the source code to be loaded into the shader\&.

.SH "DESCRIPTION"
.PP
\fBglShaderSource\fR
sets the source code in
\fIshader\fR
to the source code in the array of strings specified by
\fIstring\fR\&. Any source code previously stored in the shader object is completely replaced\&. The number of strings in the array is specified by
\fIcount\fR\&. If
\fIlength\fR
is
\fBNULL\fR, each string is assumed to be null terminated\&. If
\fIlength\fR
is a value other than
\fBNULL\fR, it points to an array containing a string length for each of the corresponding elements of
\fIstring\fR\&. Each element in the
\fIlength\fR
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\&.
.SH "NOTES"
.PP
OpenGL copies the shader source code strings when
\fBglShaderSource\fR
is called, so an application may free its copy of the source code strings immediately after the function returns\&.
.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
\fIcount\fR
is less than 0\&.
