## NAME

put\_backslash - Puts a path separator at the end of a path if needed. Allegro game programming library.

## SYNOPSIS

**#include \<allegro.h\>**

**void put\_backslash(char \*filename);**

## DESCRIPTION

If the last character of the filename is not a \`\\', \`/', \`#' or a device separator (ie. \`:' under DOS), this routine will concatenate either a \`\\' or \`/' on to it (depending on the platform). Note: ignore the function name, it's out of date.
