pointers

Hi I mash with pointers in C. I solve this problem about 5 hours and I don't know how I should continue. void InsertFirst (tList *L, int val) { tElemPtr new; if((new = malloc(sizeof(tElemPtr))) == NULL) Error(); new->data = val; new->ptr = L->frst; L->frst = new;...

restricted pointers

Hi all. I am trying to use restricted pointers to allow the gcc compiler optimize the code, but I have not been able to make it work so far. I am testing with this code: #include <stdlib.h> #include <stdio.h> #include <time.h> #include <sys/time.h> void vecmult(int n, int * restrict a, int...

Need help with the Pointers in C

I have a special character called �. When it is declared as a character variable its showing it can be printed. But when it is declared as a character pointer variable its showing it cannot be printed. I am just wondering why its happening like this.. c1 = '@'; c2 = '�'; char *fp; fp="XX�"; if...

GLGENERATEMIPMAP(3G)						    OpenGL 3.3						      GLGENERATEMIPMAP(3G)

NAME

       glGenerateMipmap - generate mipmaps for a specified texture target

C SPECIFICATION

       void glGenerateMipmap(GLenum target);

PARAMETERS

       target
	   Specifies the target to which the texture whose mimaps to generate is bound.  target must be GL_TEXTURE_1D, GL_TEXTURE_2D,
	   GL_TEXTURE_3D, GL_TEXTURE_1D_ARRAY, GL_TEXTURE_2D_ARRAY or GL_TEXTURE_CUBE_MAP.

DESCRIPTION

       glGenerateMipmap generates mipmaps for the texture attached to target of the active texture unit. For cube map textures, a
       GL_INVALID_OPERATION error is generated if the texture attached to target is not cube complete.

       Mipmap generation replaces texel array levels level base + 1 through q with arrays derived from the level base array, regardless of their
       previous contents. All other mimap arrays, including the level base array, are left unchanged by this computation.

       The internal formats of the derived mipmap arrays all match those of the level base array. The contents of the derived arrays are computed
       by repeated, filtered reduction of the level base array. For one- and two-dimensional texture arrays, each layer is filtered independently.

ERRORS

       GL_INVALID_ENUM is generated if target is not one of the accepted texture targets.

       GL_INVALID_OPERATION is generated if target is GL_TEXTURE_CUBE_MAP and the texture bound to the GL_TEXTURE_CUBE_MAP target of the active
       texture unit is not cube complete.
