mti_AskStdin()

Prompts the user for an input string.

Syntax

error_code = mti_AskStdin( buffer, prompt ) 

Returns

Name	Type	Description
error_code	int	-1 if the buffer parameter is NULL; 0 otherwise

Arguments

Name	Type	Description
buffer	char *	A pointer to a character buffer in which the user's input is returned
prompt	char *	A character string that will be used as the prompt to the user

Description

mti_AskStdin() gets input from the user by displaying the specified prompt on the vsim command line and returning what the user types. All characters entered up to, but not including, a newline character are returned in the character buffer. The character string is null-terminated. The caller is responsible for allocating the space for the buffer.
