code as below:
f_read = fopen("records/frame_read.ini", "r"); fclose(f_read);
in fact, records/frame_read.ini is not exist.
when I used gdb to debug it, appears "Program received signal SIGSEGV, Segmentation fault. 0xb7ebefc7 in flose() from /lib/i386-linux-gnu/i686/cmov/libc.so.6"
Solve it by using code as below:
f_read = fopen("records/frame_read.ini", "r"); if (f_read != NULL) fclose(f_read);
