SDDM_PSHADOW lppSddmFastRecoverShadowInit(LPP_SDDM_ENV *pSddmEnv, SDDM_PTABLE pTable, SDDM_SUB_CALLBACK shadowNotifyCallback) { SDDM_PSHADOW pShadow = NULL; SDDM_SHADOW_REG shadowReg; if((NULL == pSddmEnv) || (NULL == pTable) || (NULL == shadowNotifyCallback)) { XOS_ASSERT(0); goto error; } MEMSET(&shadowReg, 0, SIZEOF(SDDM_SHADOW_REG)); shadowReg.shadowType = SDDM_SHADOW_TYPE_FAST_RECOVERY_WRITER; shadowReg.fDataCall = shadowNotifyCallback; shadowReg.pArg = pSddmEnv; pShadow = SDDM_CreateShadow(pTable, &shadowReg); if(NULL == pShadow) { ROSNG_TRACE_WARNING("SDDM create shadow failed!!!\n"); XOS_ASSERT(0); goto error; } return pShadow; error: return NULL; } 给这段代码用c语言写一个ft测试用例

下面是一份可能的测试用例，用于测试 `lppSddmFastRecoverShadowInit` 函数的基本功能：

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include "lppSddmFastRecoverShadow.h"

/* Mock callback function */
void mock_shadow_notify_callback(SDDM_PTABLE pTable, SDDM_PSHADOW pShadow, void *pArg) {
    /* Do nothing */
}

int main() {
    LPP_SDDM_ENV sddm_env;
    SDDM_PTABLE table;
    SDDM_SUB_CALLBACK callback;
    SDDM_PSHADOW shadow;

    /* Initialize test data */
    sddm_env = (LPP_SDDM_ENV) malloc(sizeof(LPP_SDDM_ENV));
    memset(sddm_env, 0, sizeof(LPP_SDDM_ENV));
    table = (SDDM_PTABLE) malloc(sizeof(SDDM_TABLE));
    memset(table, 0, sizeof(SDDM_TABLE));
    callback = &mock_shadow_notify_callback;

    /* Test case 1: basic functionality */
    shadow = lppSddmFastRecoverShadowInit(&sddm_env, table, callback);
    if (shadow == NULL) {
        printf("Test case 1 failed: failed to create shadow\n");
        return 1;
    }

    /* Clean up */
    free(sddm_env);
    free(table);
    SDDM_CloseShadow(shadow);
    return 0;
}

需要注意的是，在实际测试中，`LPP_SDDM_ENV` 和 `SDDM_TABLE` 类型的数据需要根据具体情况进行初始化和赋值，以保证测试用例的正确性。此外，还需要为测试用例编写更多的测试场景，以覆盖函数的不同分支和边界条件。
