getservbyname programming
The getservbyname() function returns a servent structure for the entry from the database that matches the service name using protocol proto. If proto is NULL, any protocol will be matched. A connection is opened to the database if necessary. getservbyname(“ftp”, “tcp”) = 0x7fcc5248b8c0 The servent structure is defined in as follows: struct servent { char …

__fpending programming
The __fpending() function returns the number of bytes in the output buffer. For wide-oriented streams the unit is wide characters. This function is undefined on buffers in reading mode, or opened read-only. On POSIX-compliant platforms, SIGSEGV is the signal sent to a process when it makes an invalid memory reference, or segmentation fault. #include<stdio.h> #include<stdio_ext.h> …
