156 | DESCRIPTION | |
c188b0be | 157 | <<bfd_fdopenr>> is to <<bfd_fopenr>> much like <<fdopen>> is to <<fopen>>. |
b645b632 | 158 | It opens a BFD on a file already described by the @var{fd} |
70e00914 KR |
159 | supplied. |

c188b0be | 161 | When the file is later <<bfd_close>>d, the file descriptor will be closed. |
70e00914 KR |
162 | |
163 | If the caller desires that this file descriptor be cached by BFD | |
164 | (opened as needed, closed as needed to free descriptors for | |
165 | other opens), with the supplied @var{fd} used as an initial | |
baf205c4 JG |
166 | file descriptor (but subject to closure at any time), call |
167 | bfd_set_cacheable(bfd, 1) on the returned BFD. The default is to | |
70e00914 | 168 | assume no cacheing; the file descriptor will remain open until |
c188b0be | 169 | <<bfd_close>>, and will not be affected by BFD operations on other |
70e00914 | 170 | files. |
b645b632 | 171 | |
