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). SEE ALSO

NAME
index, rindex, stpcpy, strcasecmp, strcat, strchr, strcmp, strcpy, strcspn, strerror, strlen, strncasecmp, strncat, strncmp, strncpy, strpbrk, strrchr, strsep, strspn, strstr, strtok -- string specific functions LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <strings.h> char * index(const char *s, int c); char * rindex(const char *s, int c); int strcasecmp(const char *s1, const char *s2); int strncasecmp(const char *s1, const char *s2, size_t n); #include <string.h> char * stpcpy(char *dst, const char *src); char * strcat(char *restrict s1, const char *restrict s2); char * strchr(const char *s, int c); int strcmp(const char *s1, const char *s2); char * strcpy(char *restrict s1, const char *restrict s2); size_t strcspn(const char *s1, const char *s2); char * strerror(int errnum); size_t strlen(const char *s); char * strncat(char *restrict s1, const char *restrict s2, size_t n); int strncmp(const char *s1, const char *s2, size_t n); char * strncpy(char *restrict s1, const char *restrict s2, size_t n); char * strpbrk(const char *s1, const char *s2); char * strrchr(const char *s, int c); char * strsep(char **stringp, const char *delim); size_t strspn(const char *s1, const char *s2); char * strstr(const char *s1, const char *s2); char * strtok(char *restrict s1, const char *restrict s2); 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. SEE ALSO

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''). BSD
