Functions

 
PathAllocCanonicalize

Converts a path string into a canonical form.This function differs from PathCchCanonicalize and PathCchCanonicalizeEx in that it returns the result on the heap.
PathAllocCombine

Concatenates two path fragments into a single path.
PathCchAddBackslash

Adds a backslash to the end of a string to create the correct syntax for a path. (PathCchAddBackslash)
PathCchAddBackslashEx

Adds a backslash to the end of a string to create the correct syntax for a path. (PathCchAddBackslashEx)
PathCchAddExtension

Adds a file name extension to a path string.This function differs from PathAddExtension in that it accepts paths with "\", "\?" and "\?\UNC" prefixes.
PathCchAppend

Appends one path to the end of another.This function differs from PathCchAppendEx in that you are restricted to a final path of length MAX_PATH.This function differs from PathAppend in that it accepts paths with "\", "\?" and "\?\UNC" prefixes.
PathCchAppendEx

Appends one path to the end of another.This function differs from PathCchAppend in that it allows for a longer final path to be constructed.This function differs from PathAppend in that it accepts paths with "\", "\?" and "\?\UNC" prefixes.
PathCchCanonicalize

Converts a path string into a canonical form.This function differs from PathCchCanonicalizeEx in that you are restricted to a final path of length MAX_PATH.This function differs from PathAllocCanonicalize in that the caller must declare the size of the returned string, which is stored on the stack.This function differs from PathCanonicalize in that it accepts paths with "\", "\?" and "\?\UNC" prefixes.
PathCchCanonicalizeEx

Simplifies a path by removing navigation elements such as "." and ".." to produce a direct, well-formed path.This function differs from PathCchCanonicalize in that it allows for a longer final path to be constructed.This function differs from PathAllocCanonicalize in that the caller must declare the size of the returned string, which is stored on the stack.This function differs from PathCanonicalize in that it accepts paths with "\", "\?" and "\?\UNC" prefixes.
PathCchCombine

Combines two path fragments into a single path. (PathCchCombine)
PathCchCombineEx

Combines two path fragments into a single path. (PathCchCombineEx)
PathCchFindExtension

Searches a path to find its file name extension, such as ".exe" or ".ini".
PathCchIsRoot

Determines whether a path string refers to the root of a volume.This function differs from PathIsRoot in that it accepts paths with "\", "\?" and "\?\UNC" prefixes.
PathCchRemoveBackslash

Removes the trailing backslash from the end of a path string.This function differs from PathRemoveBackslash in that it accepts paths with "\", "\?" and "\?\UNC" prefixes.
PathCchRemoveBackslashEx

Removes the trailing backslash from the end of a path string.This function differs from PathCchRemoveBackslash in that it can return a pointer to the new end of the string and report the number of unused characters remaining in the buffer.This function differs from PathRemoveBackslash in that it accepts paths with "\", "\?" and "\?\UNC" prefixes.
PathCchRemoveExtension

Removes the file name extension from a path, if one is present.This function differs from PathRemoveExtension in that it accepts paths with "\", "\?" and "\?\UNC" prefixes.
PathCchRemoveFileSpec

Removes the last element in a path string, whether that element is a file name or a directory name.
PathCchRenameExtension

Replaces a file name's extension at the end of a path string with a new extension.
PathCchSkipRoot

Retrieves a pointer to the first character in a path following the drive letter or Universal Naming Convention (UNC) server/share path elements.This function differs from PathSkipRoot in that it accepts paths with "\", "\?" and "\?\UNC" prefixes.
PathCchStripPrefix

Removes the "\?" prefix, if present, from a file path.
PathCchStripToRoot

Removes all file and directory elements in a path except for the root information.This function differs from PathStripToRoot in that it accepts paths with "\", "\?" and "\?\UNC" prefixes.
PathIsUNCEx

Determines if a path string is a valid Universal Naming Convention (UNC) path, as opposed to a path based on a drive letter.This function differs from PathIsUNC in that it also allows you to extract the name of the server from the path.
