.SH "NAME"
glGetShaderInfoLog \- Returns the information log for a shader object
.SH "C SPECIFICATION"
.HP \w'void\ glGetShaderInfoLog('u
.BI "void glGetShaderInfoLog(GLuint\ " "shader" ", GLsizei\ " "maxLength" ", GLsizei\ *" "length" ", GLchar\ *" "infoLog" ");"
.SH "PARAMETERS"
.PP
\fIshader\fR
.RS 4
Specifies the shader object whose information log is to be queried\&.
.RE
.PP
\fImaxLength\fR
.RS 4
Specifies the size of the character buffer for storing the returned information log\&.
.RE
.PP
\fIlength\fR
.RS 4
Returns the length of the string returned in
\fIinfoLog\fR
(excluding the null terminator)\&.
.RE
.PP
\fIinfoLog\fR
.RS 4
Specifies an array of characters that is used to return the information log\&.
.RE
.SH "DESCRIPTION"
.PP
\fBglGetShaderInfoLog\fR
returns the information log for the specified shader object\&. The information log for a shader object is modified when the shader is compiled\&. The string that is returned will be null terminated\&.
.PP
\fBglGetShaderInfoLog\fR
returns in
\fIinfoLog\fR
as much of the information log as it can, up to a maximum of
\fImaxLength\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 information log can be obtained by calling
\fBglGetShader\fR()
with the value
\fBGL_INFO_LOG_LENGTH\fR\&.
.PP
The information log for a shader object is a string that may contain diagnostic messages, warning messages, and other information about the last compile operation\&. When a shader object is created, its information log will be a string of length 0\&.
.SH "NOTES"
.PP
The information log for a shader object is the OpenGL implementer\*(Aqs primary mechanism for conveying information about the compilation process\&. Therefore, the information log can be helpful to application developers during the development process, even when compilation is successful\&. Application developers should not expect different OpenGL implementations to produce identical information logs\&.
.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
\fImaxLength\fR
is less than 0\&.
.SH "ASSOCIATED GETS"
