.TH "al_create_vertex_buffer" "3" "" "Allegro reference manual" ""
.SH NAME
.PP
al_create_vertex_buffer \- Allegro 5 API
.SH SYNOPSIS
.IP
.nf
\f[C]
#include\ <allegro5/allegro_primitives.h>
ALLEGRO_VERTEX_BUFFER*\ al_create_vertex_buffer(ALLEGRO_VERTEX_DECL*\ decl,
\ \ \ const\ void*\ initial_data,\ int\ num_vertices,\ int\ flags)
\f[]
.fi
.SH DESCRIPTION
.PP
Creates a vertex buffer.
Can return NULL if the buffer could not be created (e.g.
the system only supports write\-only buffers).
.RS
.PP
\f[I]Note:\f[]
.PP
This is an advanced feature, often unsupported on lower\-end video
cards.
Be extra mindful of this function failing and make arrangements for
fallback drawing functionality or a nice error message for users with
such lower\-end cards.

.PP
\f[I]Parameters:\f[]
.IP \[bu] 2
decl \- Vertex type that this buffer will hold.
NULL implies that this buffer will hold ALLEGRO_VERTEX(3) vertices
.IP \[bu] 2
initial_data \- Memory buffer to copy from to initialize the vertex
buffer.
Can be \f[C]NULL\f[], in which case the buffer is uninitialized.
.IP \[bu] 2
num_vertices \- Number of vertices the buffer will hold
.IP \[bu] 2
flags \- A combination of the ALLEGRO_PRIM_BUFFER_FLAGS(3) flags
specifying how this buffer will be created.
Passing 0 is the same as passing \f[C]ALLEGRO_PRIM_BUFFER_STATIC\f[].
