VxWorks里怎樣load一個(gè)文件到內(nèi)存? 這個(gè)文件可以是在SD、USB、ATA這類的存儲(chǔ)設(shè)備，也可以通過ftp網(wǎng)絡(luò)下載;

下面是相關(guān)的實(shí)現(xiàn)代碼，分享給大家：

STATUS ldToMem
    (
    char * fileName
    )
{
        UINT8 * pData;
        FILE *  fp;
        UINT32  FileSize;


        if (NULL == (fp = fopen(fileName,"rb")))
        {
            printf("open file failure\\n");
            return ERROR;
        }


#if FALSE
        pfile = fopen("/sd0:0/fileName","rb");
#endif


        fseek (fp, 0, SEEK_END);
        FileSize = (UINT32) ftell (fp);
        fseek (fp, 0, SEEK_SET);


        if ((pData = malloc(FileSize)) == NULL)
        {
            printf("malloc failure\\n");
            return ERROR;
        }


        if (fread (pData, 1, FileSize, fp) != FileSize)
        {
            printf("malloc failure\\n");
            free(pData);
            return ERROR;
        }


        printf("ldToMem OK pointer @ 0xx FileSize %d\\n",pData, FileSize);
}
