#define LINE_BUFFER_SIZE   256

Size of the line buffer for template substitution.

Function Documentation

char** AddPair	(	char **	Keys[],
		char **	Subs[],
		char *	Key,
		char *	SubFormat,
			...
	)

Add a key-substitution pair to a key-substitution table.

Parameters

Keys	the template keys, an array of strings
Subs	the corresponding substitutions, an array of strings
Key	the new key to add
SubFormat	format string for the corresponding substitution

Returns

pointer to the new Subs string

This routine allocates memory for adding the new strings. Use FreeStringArray() to free the memory.

int FillTemplate	(	const char *	OutputFilename,
		const char *	TemplateFilename,
		char *	Keys[],
		char *	Subs[]
	)

Fill a template file according to key-substitution pairs.

Parameters

OutputFilename	the name of the filled output file
TemplateFilename	the name of the template file
Keys	the template keys, an array of strings
Subs	the corresponding substitutions, an array of strings

Returns

1 on success, 0 on failure

Fills a template file by replacing strings of the form "${KEYNAME}" with the substitution specified in Subs. The functions AddPair() and StringAppend() can be used to build the Keys and Subs arrays.

Several key-substitution pairs are provided by default:

• ${OUTPUT_FILENAME} expands to OutputFilename,
• ${TEMPLATE_FILENAME} expands to TemplateFilename,
• ${TIME} expands to the current date and time
