explain_execvp_or_die(3) FreeBSD Library Functions Manual explain_execvp_or_die(3)

explain_execvp_or_die - execute a file and report errors

#include <libexplain/execvp.h>
void explain_execvp_or_die(const char *pathname, char *const *argv);

The explain_execvp_or_die function is used to call the execvp(3) system call. On failure an explanation will be printed to stderr, obtained from explain_execvp(3), and then the process terminates by calling exit(EXIT_FAILURE).
This function is intended to be used in a fashion similar to the following example:
explain_execvp_or_die(pathname, argv);
pathname
The pathname, exactly as to be passed to the execvp(3) system call.
argv
The argv, exactly as to be passed to the execvp(3) system call.
Returns:
This function only returns on success. On failure, prints an explanation and exits.

execvp(3)
execute a file
explain_execvp(3)
explain execvp(3) errors
exit(2)
terminate the calling process
