I have a simple code which does some computation by matching string patterns.
In brief:

2. .dat files are huge text files and .txt files contain some important words.
3. I am just doing strstr to find the patterns.
4. The function returns the... (3 Replies)

glprovokingvertex
GLPROVOKINGVERTEX(3G) OpenGL 3.3 GLPROVOKINGVERTEX(3G)
NAME
glProvokingVertex - specifiy the vertex to be used as the source of data for flat shaded varyings
C SPECIFICATION
void glProvokingVertex(GLenum provokeMode);
PARAMETERS
provokeMode
Specifies the vertex to be used as the source of data for flat shaded varyings.
DESCRIPTION
Flatshading a vertex shader varying output means to assign all vetices of the primitive the same value for that output. The vertex from
which these values is derived is known as the provoking vertex and glProvokingVertex specifies which vertex is to be used as the source of
data for flat shaded varyings.
provokeMode must be either GL_FIRST_VERTEX_CONVENTION or GL_LAST_VERTEX_CONVENTION, and controls the selection of the vertex whose values
are assigned to flatshaded varying outputs. The interpretation of these values for the supported primitive types is:
If a vertex or geometry shader is active, user-defined varying outputs may be flatshaded by using the flat qualifier when declaring the
output.
NOTES
glProvokingVertex is available only if the GL version is 3.2 or greater.
ERRORS
GL_INVALID_ENUM is generated if provokeMode is not an accepted value.
