1100 * ExtractIconExA [shell32.190]
1101 *
1102 * PARAMETERS
1103 * lpszFile [in] Pointer to a null-terminated string specifying the name
1104 * of an executable file, DLL, or icon file from which
1105 * icons will be extracted.
1106 *
1107 * nIconIndex [in] Specifies the zero-based index of the first icon to
1108 * extract. For example, if this value is zero, the
1109 * function extracts the first icon in the specified file.
1110 *
1111 * If this value is -1 and phIconLarge and phiconSmall are
1112 * both NULL, the function returns the total number of
1113 * icons in the specified file. If the file is an
1114 * executable file or DLL, the return value is the number
1115 * of RT_GROUP_ICON resources. If the file is an .ico file,
1116 * the return value is 1.
1117 *
1118 * Windows 95/98, Windows NT 4.0, and Windows 2000:
1119 * If this value is a negative number and either
1120 * phIconLarge or phiconSmall is not NULL, the function
1121 * begins by extracting the icon whose resource identifier
1122 * is equal to the absolute value of nIconIndex. For
1123 * example, use -3 to extract the icon whose resource
1124 * identifier is 3.
1125 *
1126 * phiconLarge [out] Pointer to an array of icon handles that receives
1127 * handles to the large icons extracted from the file.
1128 * If this parameter is NULL, no large icons are extracted
1129 * from the file.
1130 *
1131 * phiconSmall [out] Pointer to an array of icon handles that receives
1132 * handles to the small icons extracted from the file.
1133 * If this parameter is NULL, no small icons are extracted
1134 * from the file.
1135 *
1136 * nIcons [in] Specifies the number of icons to extract from the file.
1137 *
1138 * RETURNS
1139 * If the nIconIndex parameter is -1, the phiconLarge parameter is NULL, and
1140 * the phiconSmall parameter is NULL, then the return value is the number of
1141 * icons contained in the specified file. Otherwise, the return value is the
1142 * number of icons successfully extracted from the file.
