NAME

     esetfunc, easprintf, efopen, emalloc, ecalloc, erealloc, estrdup, estrndup, estrlcat, estrlcpy, evasprintf -- error-checked utility functions

LIBRARY

     System Utilities Library (libutil, -lutil)

SYNOPSIS

     #include <util.h>

     void (*)(int, const char *, ...)
     esetfunc(void (*)(int, const char *, ...));

     int
     easprintf(char ** restrict str, const char * restrict fmt, ...);

     FILE *
     efopen(const char *p, const char *m);

     void *
     ecalloc(size_t n, size_t c);

     void *
     emalloc(size_t n);

     void *
     erealloc(void *p, size_t n);

     char *
     estrdup(const char *s);

     char *
     estrndup(const char *s, size_t len);

     size_t
     estrlcat(char *dst, const char *src, size_t len);

     size_t
     estrlcpy(char *dst, const char *src, size_t len);

     int
     evasprintf(char ** restrict str, const char * restrict fmt, ...);

DESCRIPTION

     The easprintf(), efopen(), ecalloc(), emalloc(), erealloc(), estrdup(), estrndup(), estrlcat(), estrlcpy(), and evasprintf() functions oper-
     ate exactly as the corresponding functions that do not start with an 'e' except that in case of an error, they call the installed error han-
     dler that can be configured with esetfunc().

     For the string handling functions, it is an error when the destination buffer is not large enough to hold the complete string.  For functions
     that allocate memory or open a file, it is an error when they would return a null pointer.  The default error handler is err(3).  The func-
     tion esetfunc() returns the previous error handler function.  A NULL error handler will just call exit(3).

DESCRIPTION

     The string functions manipulate strings that are terminated by a null byte.

     See the specific manual pages for more information.  For manipulating variable length generic objects as byte strings (without the null byte
     check), see bstring(3).

     Except as noted in their specific manual pages, the string functions do not test the destination for size limitations.

     strpbrk(3), strrchr(3), strsep(3), strspn(3), strstr(3), strtok(3)

STANDARDS

     The strcat(), strncat(), strchr(), strrchr(), strcmp(), strncmp(), strcpy(), strncpy(), strerror(), strlen(), strpbrk(), strspn(), strcspn(),
     strstr(), and strtok() functions conform to ISO/IEC 9899:1990 (``ISO C90'').
