Definition at line 542 of file pre.c.

PutPreVar()

int PutPreVar	(	UBYTE *	name,
		UBYTE *	value,
		UBYTE *	args,
		int	mode
	)

Inserts/Updates a preprocessor variable in the name administration.

Parameters

name	Character string with the variable name.
value	Character string with a possible value. Special case: if this argument is zero, then we have no value. Note: This is different from having an empty argument! This should only occur when the name starts with a ?
args	Character string with possible arguments.
mode	=0: always create a new name entry, =1: try to do a redefinition if possible.

Returns

Index of used entry in name list.

Preprocessor assignment. Possible arguments and values are treated and the new preprocessor variable is put into the name administration.

Parameters

s	Pointer to the character string following the preprocessor command.
mode	Bitmask. 0-bit clear: always create a new name entry, 0-bit set: try to redefine an existing name, 1-bit set: ignore preprocessor if/switch status.

Returns

zero: no errors, negative number: errors.
