在Python中调用名为`CR_GetApplicationMode`的函数，可以使用以下代码示例：

from ctypes import cdll, c_int, c_void_p, POINTER, Structure

# 加载动态链接库
lib = cdll.LoadLibrary('your_library_path')

# 定义结构体和枚举
class CR_ModeInfo(Structure):
    _fields_ = [
        ('nModeID', c_int),
        ('nImageWidth', c_int),
        ('nImageHeight', c_int),
        ('nCutoffX', c_int),
        ('nCutoffY', c_int),
        ('nBinX', c_int),
        ('nBinY', c_int),
        ('fMaxFrmRate', c_float),
        ('nMaxExpTime', c_int),
        ('nPixelDepth', c_int),
        ('nTrigTypes', c_int * 16),
        ('nTrigTypeNum', c_int),
        ('nGainLevels', c_int * 16),
        ('nGainLevelNum', c_int),
        ('nDefaultGainLevel', c_int),
        ('nRoiX', c_int),
        ('nRoiY', c_int),
        ('szDesc', c_char * 256),
    ]

class CR_TrigTypeOpt:
    CR_FluExtSync = 0x08
    CR_FluIntSync = 0x09

class CR_GainLevelOpt:
    CR_G0 = 0
    CR_G1 = 1
    CR_G2 = 2
    CR_G3 = 3
    CR_G4 = 4
    CR_G5 = 5
    CR_G6 = 6
    CR_G7 = 7

# 定义函数原型
lib.CR_GetApplicationMode.argtypes = [c_int, POINTER(CR_ModeInfo), POINTER(c_int)]
lib.CR_GetApplicationMode.restype = c_int

# 调用函数
def CR_GetApplicationMode(nDetrIdx):
    mode_info = CR_ModeInfo()
    mode_num = c_int()
    result = lib.CR_GetApplicationMode(nDetrIdx, POINTER(CR_ModeInfo)(mode_info), POINTER(c_int)(mode_num))
    return result, mode_info, mode_num.value

请注意，这里的`your_library_path`应该替换为包含`CR_GetApplicationMode`函数的动态链接库的实际路径。另外，你可能需要根据实际情况修改函数原型的参数和返回类型。在这个例子中，`nDetrIdx`是整数类型的参数，`pModeInfo`是一个指向`CR_ModeInfo`结构体的指针，`pModeNum`是一个指向整数的指针。函数返回一个整数结果、填充了信息的`CR_ModeInfo`对象和模式数量。
