| |
| ANSI_SYNOPSIS |
| #include <reent.h> |
| int _fstat_r(struct _reent *<[ptr]>, |

| |
| TRAD_SYNOPSIS |
| #include <reent.h> |
| int _fstat_r(<[ptr]>, <[fd]>, <[pstat]>) |
| struct _reent *<[ptr]>; |
| int <[fd]>; |
| struct stat *<[pstat]>; |
| |
| DESCRIPTION |
| This is a reentrant version of <<fstat>>. It |
| takes a pointer to the global data block, which holds |
| <<errno>>. |
