Retrieves a file pointer that has its boundary aligned to the regions defined by file structures. Specifically, we split four types of regions in a binary file: (1) VM and file-mapped regions, (2) VM-only regions, and (3) file-only regions, and (4) unmapped regions. A returned pointer will exclusively point to one of the first two regions, or it will be a null pointer for the rest cases. To retrieve a pointer for (3), use format-specific member functions. Case (1) is the most common case, where the address is mapped to a file offset. Case (2) is a region that has its virtual address but not mapped to the file. For example, segments in ELF files often have such a region that is only available in the VMA.

Returns an array of VM-mapped regions that have the given permission. By a VM-mapped region, we mean a region that has a corresponding mapping in the virtual memory. For example, an entire segment of an ELF file is considered a VM-mapped region.

Returns an array of VM-mapped regions. By a VM-mapped region, we mean a consecutive region that has a corresponding mapping in the virtual memory. For example, an entire segment of an ELF file is considered a VM-mapped region.

Checks if the given address is valid and there is an actual mapping from the associated binary file to the corresponding memory. Unlike IsValidAddr, this function checks if we can decide the actual value of the given address from the binary. For example, a program header of an ELF file may contain 100 bytes in size, but when it is mapped to a segment in memory, the size of the segment can be larger than the size of the program header. This function checks if the given address is in the range of the segment that has a direct mapping to the file's program header.

Checks if the given address is executable address for this binary. We say a given address is executable if the address is within an executable segment. Note we consider the addresses of known read-only sections (such as .rodata) as non-executable, even though those sections are within an executable segment. For object files, we simply consider a .text section's address range as executable.

Checks if the given address range is valid and there exists a corresponding region in the actual binary file. This function returns true only if the whole range of the addressess are valid (for every address in the range, IsAddrMappedToFile should return true).

Checks if the given address is valid for the associated binary. We say a given address is valid for the binary if the address is within the range of statically computable segment ranges.

Checks if the given address range is valid. This function returns true only if the whole range of the addressess are valid (for every address in the range, IsValidAddr should return true).

Slices the raw binary content into a read-only span of bytes of the specified length starting from the specified address.
