Function iClipString

DevIL/src-IL/src/il_states.cpp:152–171

Clips a string to a certain length and returns a new string.

// Clips a string to a certain length and returns a new string.
char *iClipString(char *String, ILuint MaxLen)
{
	char	*Clipped;
	ILuint	Length;

	if (String == NULL)
		return NULL;

	Length = ilCharStrLen(String);  //ilStrLen(String);

	Clipped = (char*)ialloc((MaxLen + 1) * sizeof(char) /*sizeof(ILchar)*/);  // Terminating NULL makes it +1.
	if (Clipped == NULL) {
		return NULL;
	}

	memcpy(Clipped, String, MaxLen * sizeof(char) /*sizeof(ILchar)*/);
	Clipped[Length] = 0;

	return Clipped;
}


// Returns format-specific strings, truncated to MaxLen (not counting the terminating NULL).
