1 | /* Function declarations for libiberty. |
2 | Written by Cygnus Support, 1994. | |
3 | ||
4 | The libiberty library provides a number of functions which are | |
5 | missing on some operating systems. We do not declare those here, | |
6 | to avoid conflicts with the system header files on operating | |
7 | systems that do support those functions. In this file we only | |
8 | declare those functions which are specific to libiberty. */ | |
