- | |
| 3161 | Parameters: |
- | |
| 3162 | * eax = 58 - function number |
- | |
| 3163 | * ebx = pointer to the information structure |
- | |
| 3164 | Format of the information structure: |
- | |
| 3165 | * +0: dword: 16 = subfunction number |
- | |
| 3166 | * +4: dword: flags: |
- | |
| 3167 | * bit 0: start the process as debugged |
- | |
| 3168 | * other bits are reserved and must be cleared |
- | |
| 3169 | * +8: dword: 0 or pointer to ASCIIZ-string with parameters |
- | |
| 3170 | * +12 = +0xC: dword: ignored |
- | |
| 3171 | * +16 = +0x10: dword: pointer to buffer for system operations |
- | |
| 3172 | (4096 bytes) |
- | |
| 3173 | * +20 = +0x14: ASCIIZ-name of file, the rules of names forming are |
- | |
| 3174 | given in the general description |
- | |
| 3175 | Returned value: |
- | |
| 3176 | * eax > 0 - the program is loaded, eax contains PID |
- | |
| 3177 | * eax < 0 - an error has occured, -eax contains |
- | |
| 3178 | file system error code |
- | |
| 3179 | Remarks: |
- | |
| 3180 | * This function is obsolete, use subfunction 7 of function 70. |
- | |
| 3181 | * Command line must be terminated by character with code 0 |
- | |
| 3182 | (ASCIIZ-string); function takes into account either all characters |
- | |
| 3183 | up to terminating null inclusively or the first 256 charachters |
- | |
| 3184 | depending on what is less. |
- | |
| 3185 | * If the process is started as debugged, it is created in |
- | |
| 3186 | the suspended state; to run use subfunction 5 of function 69. |
