ReadExecutableAtRVA(uint, uint, ref uint, byte[])

Reads module data at the specified relative virtual address

void ReadExecutableAtRVA(uint relativeVirtualAddress, uint cbData, ref uint pcbData, byte[] data)

Parameters

relativeVirtualAddress uint

The RVA to begin reading from

cbData uint

The number of bytes of data to read

pcbData uint

The number of bytes of data actually read

data byte[]

A buffer of size at least cbData which is filled with the read data

Remarks

DIA would prefer to have the following pseudo implementation of this interface: 1) If not enough of the file is available to validate image RVAs, throw any exception and return 0 bytes read 2) else if relativeVirtualAddress is not valid, throw any exception and return 0 bytes read 3) else if relativeVirtualAddress is valid, but not readable, throw any exception and return 0 bytes read 4) else if cbData is 0, return with 0 bytes read 5) else let X be the count of contiguous bytes in the virtual address space starting at relativeVirtualAddress that are at valid, readable addresses. a) If X >= cbData return S_OK and cbData bytes read. b) else if relativeVirtualAddress + X + 1 is an invalid RVA, optionally throw any exception and return X bytes read c) else if relativeVirtualAddress + X + 1 is not readable, throw any exception and return X bytes read
