XPRINTF_EXEC(3) 					   BSD Library Functions Manual 					   XPRINTF_EXEC(3)

NAME

     asxprintf_exec, dxprintf_exec, fxprintf_exec, sxprintf_exec, xprintf_exec, vasxprintf_exec, vdxprintf_exec, vfxprintf_exec, vsxprintf_exec,
     vxprintf_exec -- execute-only extensible printf execution

SYNOPSIS

     #include <printf.h>

     int
     asxprintf_exec(char ** restrict ret, printf_comp_t restrict pc, ...);

     int
     dxprintf_exec(int fd, printf_comp_t restrict pc, ...);

     int
     fxprintf_exec(FILE * restrict stream, printf_comp_t restrict pc, ...);

     int
     sxprintf_exec(char * restrict str, size_t size, printf_comp_t restrict pc, ...);

     int
     xprintf_exec(printf_comp_t restrict pc, ...);

     #include <stdarg.h>

     int
     vasxprintf_exec(char ** restrict ret, printf_comp_t restrict pc, va_list ap);

     int
     vdxprintf_exec(int fd, printf_comp_t restrict pc, va_list ap);

     int
     vfxprintf_exec(FILE * restrict stream, printf_comp_t restrict pc, va_list ap);

     int
     vsxprintf_exec(char * restrict str, size_t size, printf_comp_t restrict pc, va_list ap);

     int
     vxprintf_exec(printf_comp_t restrict pc, va_list ap);

DESCRIPTION

     These functions are execute-only, extensible printf (see xprintf(5)) variants, taking a printf_comp_t structure created by the format string
     compilation routine new_printf_comp(3).  All these variants behave like their normal printf counterparts (see printf(3)) without 'x' and
     ``_exec'' in the name (except sxprintf_exec() and vsxprintf_exec() behave like snprintf() and vsnprintf(), respectively).
