Abstract: A log acquisition method is provided that allows a processing log of software to readily be acquired and reduces the man-hours needed for analyzing a bug. The method for acquiring a runtime log of a program including at least one function for performing a predetermined process, comprising changing the address of said at least one function to the address of a function for log acquisition, wherein said function for log acquisition comprises: calling said at least one function to cause said predetermined process to be executed, receiving the result of the execution and passing said result to said program; determining whether or not a pointer parameter the type of which is specified in a predetermined manner is defined in a function definition in said program; if yes, recording a memory content pointed to by said pointer parameter as data of the specified data type.
