Introduction

[![Build Status](https://travis-ci.org/ryanflannery/exe_in_path.svg?branch=master)](https://travis-ci.org/ryanflannery/exe_in_path)

This is a small portable C (strict C89) library that simply checks the `$PATH`

environment variable for an executable. If present, it returns true. Otherwise

it returns false.

Usually you would simply `exec*` for such a check, but doing so in a `fork()`'d

child process or similar can be more complicated than it's worth for such a

common error.

Details

-------

There's a single function exported by this library

```

    bool exe_in_path(const char *e);

```

Semantics are pretty obvious.

Install

-------

Edit the variables in `Makefile` for where to install the .h and the lib.

Then

```

   $ ./configure

   $ make

   $ make install

   $ make test          /* run gtests */

```
