The 'x' prefix is in the style of xmalloc as used in many GNU packages - 
checking for errors in a safer way than the default libc API.

Most of the 'x' functions are thereby unsuitable for use in library code, 
but may be used in tests and in code that goes into the various 
executables shipped with glibc, because they exit the program on error and 
library code should generally not do that.  (The 'x' names are also not in 
the implementation namespace; non-static internal functions used within 
library code need to have reserved names such as __*.)
