mfc编程中trimleft是什么函数

针对windows平台的CString::TrimLeft(LPCTSTR lpszTargets)函数，在unix平台下自己增加该功能函数，下面是微软提供的TrimLeft函数源码:

C/C++ code void CString::TrimLeft(LPCTSTR lpszTargets)

{

// if we're not trimming anything, we're not doing any work

if (SafeStrlen(lpszTargets) == 0)

return;

CopyBeforeWrite();

LPCTSTR lpsz = m_pchData;

while (*lpsz != '\0')

{

if (_tcschr(lpszTargets, *lpsz) == NULL)

break;

lpsz = _tcsinc(lpsz);

}

if (lpsz != m_pchData)

{

// fix up data and length

int nDataLength = GetData()->nDataLength - (lpsz - m_pchData);

memmove(m_pchData, lpsz, (nDataLength+1)*sizeof(TCHAR));

GetData()->nDataLength = nDataLength;

}

}
