30 | ?S: This shell variable is used internally by Configure to check | |
31 | ?S: wether a given function is defined or not. A typical use is: | |
32 | ?S: set function d_func | |
33 | ?S: eval $inlibc | |
34 | ?S: That will print a message, saying wether function was found or | |
35 | ?S: not and set d_func accordingly. | |
