void GetCodeInfo(lpProc,lpSegInfo)
This function retrieves a pointer to an array of 16-bit values containing information about the code segment that contains the function pointed to by the lpProc parameter.
| Parameter | Type/Description |
| lpProc | FARPROC Is the address of the function in the segment for which information is to be retrieved. Instead of a segment:offset address, this value can also be in the form of a module handle and segment number. The GetModuleHandle function returns the handle of a named module. | |
| lpSegInfo | LPVOID Points to an array of four 32-bit values that will be filled with information about the code segment. See the following “Comments” section for a description of the values in this array. |
None.
The lpSegInfo parameter points to an array of four 32-bit values that contains such infor-mation as the location and size of the segment and its attributes. The following list describes each of these values:
| Offset | Description |
| 0 | Specifies the logical-sector offset (in bytes) to the contents of the segment data, relative to the beginning of the file. Zero means no file data is available. | |
| 2 | Specifies the length of the segment in the file (in bytes). Zero means 64K. | |
| 4 | Contains flags which specify attributes of the segment. The following list describes these flags: |
| Bit | Meaning | ||
| 0–2 | Specifies the segment type. If bit 0 is set to 1, the segment is a data segment. Otherwise, the segment is a code segment. | ||
| 3 | Specifies whether segment data is iterated. When this bit set to 1, the segment data is iterated. | ||
| 4 | Specifies whether the segment is moveable or fixed. When this bit is set to 1, the segment is moveable. Otherwise, it is fixed. | ||
| 5 | Is not returned. | ||
| 6 | Is not returned. | ||
| 7 | Specifies whether the segment is a read-only data segment or an execute-only code segment. If this bit is set to 1 and the segment is a code segment, the segment is an execute-only segment. If this bit is set to zero and the segment is a data segment, it is a read-only segment. | ||
| 8 | Specifies whether the segment has associated relocation information. If this bit is set to 1, the segment has relocation information. Otherwise, the segment does not have relocation information. | ||
| 9 | Specifies whether the segment has debugging information. If this bit is set to 1, the segment has debugging information. Otherwise, the segment does not have debugging information. | ||
| 10–11 | Is not returned. | ||
| 12–15 | Is not returned. | ||
| 6 | Specifies the total amount of memory allocated for the segment. This amount may exceed the actual size of the segment. Zero means 65,536. | ||
