ENUMRESNAMEPROCA callback function (libloaderapi.h)
An application-defined callback function used with the EnumResourceNames and EnumResourceNamesEx functions. It receives the type and name of a resource. The ENUMRESNAMEPROC type defines a pointer to this callback function. EnumResNameProc is a placeholder for the application-defined function name.
Syntax
ENUMRESNAMEPROCA Enumresnameproca;
BOOL Enumresnameproca(
[in, optional] HMODULE hModule,
LPCSTR lpType,
LPSTR lpName,
[in] LONG_PTR lParam
)
{...}
Parameters
[in, optional] hModule
Type: HMODULE
A handle to the module whose executable file contains the resources that are being enumerated. If this parameter is NULL, the function enumerates the resource names in the module used to create the current process.
lpType
Type: LPCTSTR
The type of resource for which the name is being enumerated. Alternately, rather than a pointer, this parameter can be MAKEINTRESOURCE(ID), where ID is an integer value representing a predefined resource type. For standard resource types, see Resource Types. For more information, see the Remarks section below.
lpName
Type: LPTSTR
The name of a resource of the type being enumerated. Alternately, rather than a pointer, this parameter can be MAKEINTRESOURCE(ID), where ID is the integer identifier of the resource. For more information, see the Remarks section below.
[in] lParam
Type: LONG_PTR
An application-defined parameter passed to the EnumResourceNames or EnumResourceNamesEx function. This parameter can be used in error checking.
Return value
Type: BOOL
Returns TRUE to continue enumeration or FALSE to stop enumeration.
Remarks
If IS_INTRESOURCE(lpszType) is TRUE, then lpszType specifies the integer identifier of the given resource type. Otherwise, it is a pointer to a null-terminated string. If the first character of the string is a pound sign (#), then the remaining characters represent a decimal number that specifies the integer identifier of the resource type. For example, the string "#258" represents the identifier 258.
Similarly, if IS_INTRESOURCE(lpszName) is TRUE, then lpszName specifies the integer identifier of the given resource. Otherwise, it is a pointer to a null-terminated string. If the first character of the string is a pound sign (#), then the remaining characters represent a decimal number that specifies the integer identifier of the resource.
An application must register this function by passing its address to the EnumResourceNames or EnumResourceNamesEx function.
If the callback function returns FALSE, then EnumResourceNames or EnumResourceNamesEx will stop enumeration and return FALSE. On Windows XP and earlier the value obtained from GetLastError will be ERROR_SUCCESS; starting with Windows Vista, the last error value will be ERROR_RESOURCE_ENUM_USER_STOP.
Note
The libloaderapi.h header defines ENUMRESNAMEPROC as an alias that automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that is not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
