Need to find size of destination buffer for strncpy
Mohansnayaka 28 December 2006 23:40:44
	Hi all, We are using strcpy to copy strings in our app. This gave us problems when the destination buffer is not large enough. As a workaround, we wanted to replace calls to strcpy with strncpy. That is, replace calls to strcpy with say, my_strcpy(dest,src) which will internally find the destination buffer length. For this we need to know the destination buffer size. For statically allocated strings sizeof is returning the length of the array correctly, but not for malloced strings (char). Hence we are not able to replace calls to strcpy with strncpy with appropriate length parameter. Is there any other way out? Changing all the static and dynamic allocations in the application is very very difficult (around 15k instances will have to be changed).
