DESCRIPTION
The assert() macro tests the given expression and if it is false, the
calling process is terminated. A diagnostic message is written to stderr
and the function abort(3) is called, effectively terminating the program.
If expression is true, the assert() macro does nothing.
The assert() macro may be removed at compile time by defining NDEBUG as a
macro (e.g., by using the cc(1) option -DNDEBUG).
EXAMPLES
The assertion:
assert(1 == 0);
generates a diagnostic message similar to the following:
Assertion failed: (1 == 0), function main, file assertion.c, line
100.
int SetFilePath(const char * filePath)
{
assert(NULL != filePath);//如果强制要使用传入filePath
return 0;
}
int SetFilePath(const char * filePath)
{
if (NULL == filePath)//如果有默认的filePath
{
//set default file path
}
else
{
}
return 0;
}
