int Assemble(char *cmd,ulong ip,t_asmmodel *model,int attempt,int constsize,char *errtext);

Parameters:

cmd - pointer to zero terminated ASCII command;
pi - address of the first byte of generated binary command in memory;
model - pointer to the structure that receives machine code and mask, see detailed description below;
attempt - index of alternative encoding of the command. Call Assemble with attempt=0,1,2... to obtain all possible versions of the command. Stop this sequence when Assemble reports error;
constsize - requested size of address constant and immediate data. Call Assemble with constsize=0,1,2,3 to obtain all possible encodings of the version selected by attempt;
errtext - pointer to text buffer of length at least TEXTLEN bytes that receives description of detected error.
t_asmmodel: structure that receives assembled code.
typedef struct t_asmmodel {    // Model to search for assembler command
    char code[MAXCMDSIZE];     // Binary code
    char mask[MAXCMDSIZE];     // Mask for binary code (0: bit ignored)
    int length;                // Length of code, bytes (0: empty)
    int jmpsize;               // Offset size if relative jump
    int jmpoffset;             // Offset relative to IP
    int jmppos;                // Position of jump offset in command
} t_asmmodel;

Members:

int Assemble(char *cmd,ulong ip,t_asmmodel *model,int attempt,int constsize,char *errtext);

把ASCII 的代码 比如 "push eax"这类转化成对应的机器码.....
都正常,  就是转化 "push 256" 或者  "STC" 这样的带立即数或者符合的都说不支持......
使用过这个函数的朋友指点下........

已解决:

int attempt,int constsize  置0即可.....为什么...不大懂....  等E文不错的朋友说说
