OpenGLUT - fonts

#include <openglut.h>

float

glutStrokeLength(void *fontID, const unsigned char *string);

fontID A GLUT stroked font identifier.

string A C-style (NUL-terminated) string.

This function reports the sum of the widths of the characters in a string, using the font metrics of a given font.

Like glutStrokeString(), glutStrokeLength() respects newlines in the input.

Returns 0 if: - The fontID is out of range. - The string is NULL. - All characters in the string are zero-width.

Refer to glutStrokeWidth() for notes on the nature of this function's return value, and for comparisons to old GLUT and freeglut.
