mg_mk_str

struct mg_str mg_mk_str(const char *s);

Helper function for creating mg_str struct from plain C string. NULL is allowed and becomes {NULL, 0}.

mg_mk_str_n

struct mg_str mg_mk_str_n(const char *s, size_t len);

Like mg_mk_str, but takes string length explicitly.

MG_MK_STR

#define MG_MK_STR(str_literal) \
  { str_literal, sizeof(str_literal) - 1 }
#define MG_MK_STR_N(str_literal, len) \
  { str_literal, len }
#define MG_NULL_STR \
  { NULL, 0 }

Macro for initializing mg_str.

mg_vcmp

int mg_vcmp(const struct mg_str *str2, const char *str1);

Cross-platform version of strcmp() where where first string is specified by struct mg_str.

mg_vcasecmp

int mg_vcasecmp(const struct mg_str *str2, const char *str1);

Cross-platform version of strncasecmp() where first string is specified by struct mg_str.

mg_strdup

struct mg_str mg_strdup(const struct mg_str s);

Creates a copy of s (heap-allocated).

mg_strdup_nul

struct mg_str mg_strdup_nul(const struct mg_str s);

Creates a copy of s (heap-allocated). Resulting string is NUL-terminated (but NUL is not included in len).

mg_strchr

const char *mg_strchr(const struct mg_str s, int c);

Locates character in a string.

mg_strcmp

int mg_strcmp(const struct mg_str str1, const struct mg_str str2);

Compare two mg_strs; return value is the same as strcmp.

mg_strncmp

int mg_strncmp(const struct mg_str str1, const struct mg_str str2, size_t n);

Like mg_strcmp, but compares at most n characters.

mg_strcasecmp

int mg_strcasecmp(const struct mg_str str1, const struct mg_str str2);

Compare two mg_strs ignoreing case; return value is the same as strcmp.

mg_strfree

void mg_strfree(struct mg_str *s);

Free the string (assuming it was heap allocated).

mg_strstr

const char *mg_strstr(const struct mg_str haystack, const struct mg_str needle);

Finds the first occurrence of a substring needle in the haystack.

mg_strstrip

struct mg_str mg_strstrip(struct mg_str s);

Strip whitespace at the start and the end of s

mg_str_starts_with

int mg_str_starts_with(struct mg_str s, struct mg_str prefix);

Returns 1 if s starts with the given prefix.
