Create a temporary C string and return a pointer to it. The space allocated to the C string is ‘length’ characters and is initialized to the null string.

pointer = cnfCreat( length )

int length (Given)

char $\ast$cnfCreat

• If the argument is given as N then there is room to store N-1 characters plus a trailing null character in a C string.

• If the routine could not create the space, then it returns a null pointer.
