Important Notice
The pages on this site contain documentation for very old MS-DOS software,

you should not rely on the information found here, as it will be woefully
out of date.

#define INCL_DOSMISC
USHORT DosQSysInfo(index, pbSysInfoBuf, cbSysInfoBuf)
USHORT index; /* index of value to look up */
PBYTE pbSysInfoBuf; /* pointer to buffer receiving information */
USHORT cbSysInfoBuf; /* number of bytes in buffer receiving information */
The DosQSysInfo function retrieves system-format information, such as
maximum path length, that is constant for a particular release of MS OS/2.
Parameter Description
────────────────────────────────────────────────────────────────────────────
index Specifies the index of the information to retrieve. Currently,
the only available index is Q_MAX_PATH_LENGTH, which returns
the maximum path length (including the trailing null
character).
pbSysInfoBuf Points to the buffer that receives the system information.
When the value of the index is Q_MAX_PATH_LENGTH, the
DosQSysInfo function puts the maximum path length into the
first two bytes of the buffer.
cbSysInfoBuf Specifies the length (in bytes) of the buffer to receive the
system information.
Return Value
The return value is zero if the function is successful. Otherwise, it is an
error value, which may be one of the following:
ERROR_BUFFER_OVERFLOW
ERROR_INVALID_PARAMETER
